The armed group, Boko Haram is suspected to have carried out an attack targeting Shia Muslims marking the Islamic religious holy day of Ashoura in northeastern Nigeria.

The group which is based in the region has stepped up attacks in recent weeks.

Thousands of people have been forced out of the town of Mubi after it fell to the group last week, and hundreds are still missing.
