Two female suicide bombers kill 13 people in separate blasts
Two female suicide bombers have killed 13 people at a crowded market and a military checkpoint in north-eastern Nigeria, according to witnesses.
It is the fourth attack this week in which more than 160 have been killed as Boko Haram extremists appear to be following an Islamic State group order to step up attacks in the holy month of Ramadan.
In the most deadly attack, militants targeted several mosques in north-eastern Kukawa town on Tuesday and gunned down nearly 100 praying worshippers.
Security guard Abba Shehu said the latest attacks began with an explosion involving a teenage girl at Malari village market outside Maiduguri city. He said at least 10 people were killed.
Minutes later a woman in a taxi blew up at a military checkpoint, killing a soldier and two passengers.
