New Covid-19 variant C.1.2 found in 6 countries, can be more infectious; says scientists

A new variant of SARS-CoV-2, C.1.2, has been detected in South Africa and many other countries globally which could be transmissible and shun protection provided by Covid-19 vaccines, according to the study.

A new variant of SARS-CoV-2, C.1.2, has been detected in South Africa and many other countries globally which could be transmissible and shun protection provided by Covid-19 vaccines, according to the study.

Scientists from National Institute for Communicable Diseases (NICD), KwaZulu-Natal Research Innovation, and Sequencing Platform (KRISP) in South Africa said the potential variant of interest, C.1.2, was first identified in the country in May this year. The variant has since been detected in China, the Democratic Republic of the Congo, Mauritius, England, New Zealand, Portugal, and Switzerland as of August 13, researchers said.

The study on the newly detected variant is yet to be peer-reviewed and was posted on the pre-print repository MedRxiv on August 24. According to the study, C.1.2 has mutated substantially compared to C.1, one of the variants which dominated the SARS-CoV-2 infections in the first wave of South Africa. C.1.2 has more mutations than other variants of concerns or variants of interest detected globally so far, researchers said.

According to the authors of the research, this rise is similar to the increase observed with the Beta and Delta variants in South Africa during the early stages of their detection. The authors noted that there have been consistent increases in the number of C.1.2 genomes in South Africa each month, rising from 0.2 per cent of genomes sequenced in May to 1.6 per cent in June and then to 2 per cent in July.

The mutations N440K and Y449H, which have been associated with immune escape from certain antibodies, have also been noticed in C.1.2 sequences.

“While these mutations are not characteristic of current VOCs/VOIs, they have been associated with escape from certain class 3 neutralising antibodies,” the authors wrote.

Meanwhile, 713,089 new Covid-19 cases have been registered and 10,854 people have succumbed to the virus globally. There are 214.6 million confirmed cases worldwide. India on Tuesday reported 30,941 new Covid-19 cases in the last 24 hours, surging the overall Covid-tally to 32,768,880, according to the data released by the Union health ministry at 9 am.

Israel-Lebanon ceasefire to begin within hours as Trump announces 10-day truce

Israel and Lebanon may begin a 10-day ceasefire within hours after a proposal announced by Donald Trump amid ongoing tensions.

Donald Trump

A temporary halt in hostilities between Israel and Lebanon is expected to begin within hours after US President Donald Trump announced a proposed 10-day ceasefire between the two sides, amid ongoing tensions in the region.

According to his statement, the ceasefire is likely to take effect around 5 p.m. Eastern Time, although independent confirmation from both sides is still awaited.

The development follows discussions involving Israeli Prime Minister Benjamin Netanyahu and Lebanese President Joseph Aoun, with mediation efforts led by the United States.

Officials indicated that the proposed truce is aimed at creating a limited window to reduce violence and potentially pave the way for broader diplomatic engagement. The situation along the Israel-Lebanon border has remained tense in recent weeks, with escalation linked to the activities of Hezbollah.

Diplomatic efforts have intensified in recent days, with discussions facilitated by the United States, including the involvement of US Secretary of State Marco Rubio. However, details of the agreement and the extent of coordination between the parties remain unclear.

The situation remains fluid, and the success of the ceasefire will depend on adherence by all sides involved. The conflict has already led to significant humanitarian and geopolitical consequences, including displacement and disruption in affected areas.

While the proposed ceasefire is being seen as an important step toward de-escalation, broader negotiations involving regional stakeholders are expected to be necessary for any lasting resolution.

US ends oil sanctions waiver for Iran and Russia, impact likely on India’s energy imports

The US decision to end the Iran and Russia oil waiver may impact India’s oil imports, fuel prices and global energy markets.

US oil tanker

The United States has decided not to extend a temporary sanctions waiver that allowed limited trade in Iranian and Russian oil, marking a shift towards stricter enforcement of economic restrictions.

The waiver, introduced in March 2026, had permitted the sale of oil already loaded on ships to stabilise global supply during heightened geopolitical tensions. However, it is now set to expire around mid-April without renewal.

US officials have indicated that the move is part of a broader strategy to increase pressure on both Iran and Russia amid ongoing conflicts and geopolitical tensions.

What the waiver did and why it mattered

The short-term waiver allowed millions of barrels of oil—estimated at around 140 million barrels—to enter global markets, helping ease supply shortages and prevent sharp price spikes.

It also enabled countries like India to purchase discounted crude oil from Russia and resume limited imports from Iran after years of restrictions.

Impact on India

India, one of the world’s largest oil importers, is expected to feel the impact of the decision in several ways:

  • Reduced access to discounted oil
    India had been buying cheaper Russian crude and recently resumed Iranian imports under the waiver. Its end may limit these options.
  • Potential rise in fuel costs
    With fewer discounted supplies available, India may need to rely more on costlier sources, which could increase domestic fuel prices.
  • Supply diversification pressure
    India may need to explore alternative suppliers in the Middle East, Africa, or the US to maintain energy security.
  • Geopolitical balancing challenge
    The move adds pressure on India to align with US sanctions while managing its own economic interests.

Global energy market concerns

The end of the waiver comes at a time when global oil markets are already under stress due to conflict in West Asia and disruptions in key routes like the Strait of Hormuz.

Analysts warn that tightening sanctions could:

  • Reduce global oil supply
  • Increase price volatility
  • Intensify competition among major buyers like India and China

Bigger picture

The US decision reflects a broader shift from temporary relief measures to stricter enforcement of sanctions, even if it risks tightening global energy markets.

For India, the development highlights a recurring challenge—balancing affordable energy access with geopolitical realities.

Sanctioned tanker fails to breach US blockade, turns back near Strait of Hormuz

A US-sanctioned tanker failed to cross the Hormuz blockade and turned back, underscoring rising tensions and disruption in global shipping routes.

A US-sanctioned oil tanker failed to break through a newly imposed American naval blockade and was forced to turn back near the Strait of Hormuz, highlighting growing tensions in the region.

The vessel, identified as the Rich Starry, reversed its course after attempting to exit the Gulf, according to shipping data. The development comes just days after the United States enforced restrictions on ships linked to Iranian ports.

The blockade was announced by Donald Trump following the collapse of recent diplomatic talks with Iran. The move aims to restrict maritime traffic associated with Iranian trade.

Officials said that during the first 24 hours of enforcement, no vessel successfully crossed the blockade. Several ships, including the sanctioned tanker, complied with instructions from US forces and turned back toward regional waters.

The tanker is reported to be linked to a Chinese company previously sanctioned for dealing with Iran. It was carrying a cargo of methanol loaded from the United Arab Emirates at the time of the incident.

The situation underscores the rising risks in one of the world’s most critical oil transit routes. The Strait of Hormuz typically handles a significant share of global energy shipments, but traffic has sharply declined due to ongoing geopolitical tensions.

The blockade, which applies specifically to vessels travelling to or from Iranian ports, has added further uncertainty for shipping companies, insurers and global energy markets.
