The Islamist extremist group Boko Haram have said they carried out a wave of fatal Christmas Day bombings against churches in Nigeria, and have warned there is more to come.
There have been five attacks so far. At least 28 people have been killed and scores more wounded.
The first was just outside the capital Abuja. One eyewitness said the bomb exploded in the middle of St Theresa’s church during Christmas Mass. Another said the windows of her house nearby were blown out.
Officials said at least 25 people died in that attack.
Shortly afterwards a church in Jos was bombed killing a policeman. Then Gadaka in the north east was hit and there were two explosions in Damaturu also in the predominantly Muslim north.
Boko Haram is loosely based on the Taliban and began its activities in 2003 demanding sharia law throughout Nigeria.
In August it targeted the UN building in Abuja.
Some of its worst attacks were last month in Damaturu and Potiskum where at least 65 people were killed
