Suspected Boko Haram suicide bombers have killed at least 13 other people in an attack on a market in the northeast Nigerian town of Biu in Borno state, Reuters reported quoting officials.

The blasts struck while aid workers were distributing food to people affected by the eight-year conflict with Boko Haram, said Aliyu Idrisa, a community leader.

In addition to the 13 victims, 53 people were injured and two bombers were killed, said Victor Isuku, police spokesman for Borno state.

Saturday’s attack bore the hallmarks of Boko Haram, which uses suicide bombers, often women and girls, to attack crowded public spaces.
