At least 44 worshippers have been shot dead at a mosque in north-eastern Nigeria, officials in Borno state have said.
The killings took place during dawn prayers on Sunday, although news only emerged on Monday, as communications are disrupted by a state of emergency.
The attack occurred in the town of Konduga, 35km (22 miles) from the state capital, Maiduguri.
The BBC's Will Ross described the attack as "surprising".
