There were two bomb attacks on the central Nigerian city of Jos which left at least 44 people dead on Sunday night, the authorities say.
No-one has claimed responsibility but militant group Boko Haram has attacked Jos before, even though it is not in north-east Nigeria where the Islamists normally operate.
The blasts are the latest in a series of deadly attacks in recent days which have seen more than 200 people killed.
The attacks came shortly after the Ramadan fast was broken, with both sites full of people. Of the 44 dead, 23 were killed at the restaurant and 21 at the mosque, Nigeria’s National Emergency Management Agency (Nema) says.
There are also 47 people being treated for injuries, but emergency officials are still gathering information, so the figures may rise.
The blast at the restaurant was caused by a bomb that had been planted, whereas the mosque was attacked by a suicide bomber and that explosion was preceded by gunfire, the BBC’s Ishaq Khalid reports.
Our correspondent says that many believe that the mosque’s imam, who was preaching at the time, may have been the target.
Sheikh Muhammad Sani Yahya Jingir, who survived the attack, is known for preaching against Boko Haram and has written a book, which criticises the group, called Boko Halal (Western education is permitted, Boko Haram means Western education is forbidden).
He has survived a previous assassination attempt at his home and is seen as one of the most influential clerics in Nigeria.
