At least 30 people have been killed in a triple suicide attack in northeast Nigerian state of Borno, state emergency officials said on Monday, in the biggest mass killing this year by suicide bombers.

No group has yet claimed responsibility for the attack.

The Boko Haram group and its Islamic State splinter group have often carried out attacks targeting civilians and the military in Borno state. Their attacks have claimed hundreds of thousands of lives and displaced millions of people.

“Yesterday around 8pm (1900 GMT) it was reported that there was a very loud explosion in (the village of) Konduga. On reaching the scene of the incident we found there was a lot of casualties. In fact the death toll was over 30 and the injured over 42,” an emergency service official told Reuters.

The military did not respond to a request for comment.
