The air strike, which hit the remote Tumfa market in Zurmi district on Sunday, was the second to kill scores of people at a ​crowded market in northern Nigeria in a month.

Dozens of injured ​people were being treated at hospitals in Zurmi and nearby ⁠Shinkafi, Amnesty said, adding that many of those killed were ​women and girls.

The Nigerian military did not immediately respond to requests for ​comment but has previously denied targeting civilians, saying airstrikes are intelligence-led and hit only militant targets.

Citing witnesses, Amnesty said military jets had been spotted hovering around the ​area at midday and returned about two hours later and struck ​the crowded market.

In April, around 200 civilians were killed in a similar airstrike on ‌a ⁠weekly market in Jilli, in northeastern Nigeria.

The military has opened a probe into that incident.

Residents say they are increasingly worried about civilian deaths from military raids and strikes in northern regions.

Nigeria’s military has been battling ​banditry in the ​northwest and a ⁠17-year insurgency in the northeast.

The United States struck what it said were militant bases in ​northwestern Nigeria on Christmas Day last year, after President ​Donald ⁠Trump accused Nigeria of failing to protect Christians.

“This pattern of human rights violation is increasingly becoming the norm, with villagers at the receiving end ⁠of ​atrocities by both armed groups, bandits and ​the military,” Amnesty said.

It called the air strikes unlawful and said they showed disregard for civilian ​life.
