A Nigerian Air Force strike targeting jihadi rebels hit a local market in northeastern Nigeria, killing over 100 civilians including children and injuring many others, a rights group and local media reported on Sunday. Officials confirmed a misfire without providing details. Amnesty International cited survivors as saying that at least 100 people were killed in the airstrike on Saturday on a village in Yobe state, near the border with Borno state, which is the epicenter of the jihadi insurgency that has ravaged the region for over a decade.

"We have their pictures and they include children," Isa Sanusi, Amnesty International's Nigeria director, told AP. A worker at the Geidam General hospital, in Yobe, said at least 23 people injured in the incident were receiving treatment. According to an AP tally of reported deaths, at least 500 civilians have died since 2017 in such misfires in Nigeria, where the military often conducts air raids to battle armed groups who control vast forest enclaves.

The leaders of China and Spain pledged to work to safeguard multilateralism at a time of conflicts including the war in Iran, with Chinese President Xi Jinping saying the countries should "oppose the world's retrogression to the law of the jungle." Xi said they should "jointly safeguard genuine multilateralism," strengthen communication and cooperate closely, during a reception for Spanish Prime Minister Pedro Sánchez at the Great Hall of the People.

Sánchez agreed and said China and Spain "can contribute to finding solutions to the various trade tensions that exist, to the geopolitical difficulties and complexities of today's world, to the wars, to the environmental and social challenges that afflict the world." Sánchez is on his fourth trip in just over three years to the world's second-largest economy. Spain is looking to strengthen political and commercial ties. The visit comes as Sánchez faces a strained relationship with the U.S. over his opposition to the war in Iran.

North Korean leader Kim Jong Un observed a test of an upgraded solid-fuel engine for weapons capable of reaching the US mainland, state media reported this week. While the test was in line with Kim's stated goal of acquiring more agile, hard-to-detect missiles targeting the US and its allies, some experts speculate North Korea's claim may be an exaggeration. Missiles with built-in solid propellants are easier to move and conceal their launches than liquid-fuel weapons, which in general must be fueled before liftoffs and cannot last long.

The official Korean Central News Agency reported Kim watched the ground jet test of the engine using a composite carbon fiber material. It said the engine's maximum thrust is 2,500 kilonewtons, up from about 1,970 kilonewtons reported in a similar solid-fuel engine test in September. KCNA reported the test was conducted as part of the country's five-year arms build-up meant to upgrade "strategic strike means," a term referring to nuclear-capable ballistic missiles and other weapons.

The BBC is to cut as many as 2,000 jobs in the biggest downsizing of the public service broadcaster in 15 years. Staff were informed of the cuts, which will affect about 10% of the BBC's 21,500 employees, at an all-staff meeting this week. The round of job losses, the biggest at the BBC since 2011, is being set in motion before the former top Google executive Matt Brittin takes over as director general next month. The corporation announced a £600m cost-cutting plan in February, saying that it would involve a reduction in headcount and the end of some programming.

Tim Davie, the outgoing director general, said at the time that the BBC would need to cut 10% of its approximately £6bn annual cost base over the next three years. Davie left the BBC on 2 April, having announced his resignation in November after controversy over coverage of issues including Donald Trump, Gaza and trans rights.
