Maiduguri - Gunmen killed at least 22 people at a village market in Borno State, a security official said on Monday, in what was likely the latest attack by Boko Haram.
The attack on the remote village of Daku, an area bordering Chibok, started on Sunday, said the official who asked not to be named. The gunmen arrived in a military column and brandished AK-47s, which was similar to previous Boko Haram attacks.
"My brother who travelled to the village was caught up in the incident but was lucky to escape," Manaseh Adamu, a resident of Maiduguri, told Reuters. "He told me some Boko Haram members started shooting into the market.
Separately, at least four people were killed and houses torched in unrelated ethnic clashes between rival groups in Taraba state, other security officials said.
These clashes did not appear to be the work of Boko Haram.
Youths burned down two kiosks in a Muslim community in the small commercial town of Wukari early on Sunday, sparking the violence, Taraba state police spokesman Joseph Kwaji said.
Gunshots were later heard and numerous houses torched, Kwaji said, adding that four people were confirmed killed.
Nigerian media reported that more than 25 people were feared dead after the clash, although Reuters was unable to independently verify that number. Last year similar clashes in Wukari killed at least 39 people.
