Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

Israel has launched a new act of aggression on a residential neighborhood in Lebanon's capital, Beirut, killing and injuring about two dozen civilians.

The Israeli regime's military said in a statement that its forces carried out a so-called precise strike in a residential apartment in Dahiyeh in the southern suburbs of Beirut on Sunday.

The aggression targeted residential areas, killing at least five people and injuring more than 28 people, Lebanon's Health Ministry said. 

Hezbollah announced the martyrdom of senior Hezbollah commander Haytham Ali Tabatabai and four resistance fighters.

Lebanese President Michel Aoun condemned the airstrike, calling it a clear demonstration of Tel Aviv’s disregard for repeated international calls to halt violations on Lebanese soil.

“Israel refuses to implement international resolutions and all efforts aimed at ending the escalation and restoring stability,” Aoun said, urging the international community to take action to prevent further aggression.

The Palestinian Islamic Jihad movement also condemned the attack, holding the international community accountable. 

“The international community bears responsibility and continues to provide cover for these attacks as long as it does not restrain the occupiers,” said Ali Abu Shahin, a member of the group’s political bureau.

Israeli prime minister Benjamin Netanyahu’s office announced that the Israeli army carried out a strike “in the heart of Beirut."

Netanyahu reportedly approved the operation following recommendations from top Israeli security officials.

Two senior US officials commented on the Israeli strike.

The first official said that Israel did not notify Americans in advance about the attack. "We were informed immediately after the strike was carried out."

The second senior official said that the "US knew for several days that Israel was planning to escalate its strikes in Lebanon, but did not know in advance the timing, location, or target of the strike."

Speaking from the site of the Israeli strike, Lebanese MP Ali Ammar condemned the attack as part of a broader campaign of aggression that has targeted "all of Lebanon since the Washington-sponsored ceasefire."

He stated that "any attack on Lebanon is a violation of red lines; this aggression is part and parcel of the entity that targets Lebanon's dignity, sovereignty, and security of citizens."

Ammar went on to say the resistance is responding with "utmost wisdom, patience, and will confront the enemy at the appropriate time."

"Unfortunately, the enemy is emboldened to commit its aggression by voices within Lebanon that have turned themselves into tools that support its aggression," he added.

The Israeli attack on the southern suburbs of the Lebanese capital is the latest blatant violation of the ceasefire Israel signed with Hezbollah in November 2024, which was intended to end hostilities that had escalated into full-scale war.

An Israeli strike on the Ain al-Hilweh camp near Sidon in southern Lebanon late Tuesday killed at least 14 people. It wounded several others, including young students, according to the Lebanese health ministry.

The military claimed the attack targeted “a Hamas training compound” used to plan and carry out attacks against the regime -- a claim that has frequently been made without evidence.

Hamas rejected the allegations as “a blatant lie aimed at justifying the massacre,” stating it had “no military installations in the Palestinian camps in Lebanon” and that the targeted site was merely “an open sports field.”

According to Lebanese authorities, Israeli attacks have killed approximately 4,000 people and displaced more than 1.2 million residents across the country since October 2023.

Bengaluru: 'Nati koli saaru' (country chicken curry) considered one of Chief Minister Siddaramaiah’s favourites along with steaming hot idlis was on the breakfast menu at Deputy CM D K Shivakumar’s residence on Tuesday, according to official sources.

The spread also included 'nati koli' fry, vada and pongal, among other items, they said.

In an apparent show of unity, Siddaramaiah visited Shivakumar’s residence for breakfast, just days after the two leaders shared a meal amid a simmering power tussle in the state Congress.

Siddaramaiah drove to the Deputy CM’s residence in Sadashivanagar, where he was received by Shivakumar and his brother D K Suresh, who is a former Congress MP.

Suresh and Kunigal MLA H D Ranganath, a relative of Shivakumar, joined them for breakfast, which featured a mix of vegetarian and non-vegetarian dishes.

Speaking to reporters later, Siddaramaiah said Shivakumar had invited him during his visit to the CM’s residence for breakfast on Saturday.

Asked about the difference between the two meals, the chief minister said, "At his (Shivakumar’s) house it was non-veg, while at my house it was veg. He is a vegetarian, I am a non-vegetarian. I had not prepared non-veg. I told DK to get chicken from the village as you won’t get the original in Bengaluru."

Shivakumar said he had initially invited Siddaramaiah to his residence, but the CM had suggested visiting his place first and reciprocating later. "It was a vegetarian breakfast at the CM’s house on Saturday," he noted.

"Today, I invited him (the CM) to my house. He enjoyed the breakfast, which had his Mysuru taste," Shivakumar added. At this point, Siddaramaiah remarked that Shivakumar’s wife is also from Mysuru.

Saturday’s breakfast at Siddaramaiah’s official residence, held as part of efforts by the Congress high command to ease tensions in the leadership dispute between the two, reportedly included idlis and sambar, according to official sources.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.
