At least 118 people were killed in a double bombing in Jos on May 20, with the first bomb detonated at 3pm, the second around half an hour later in a busy market area; then on May 21 Boko Haram gunmen attacked two villages in southern Borno State, killing over 40 people.
On May 18, at least five people were killed in a blast in the predominantly Christian Sabon Gari district of Kano in the North. A girl aged around 12 was among those killed. Kano police said five people – including the bomber – died in the blast, but Christian sources put the death toll at around 20.
Islamist militant group Boko Haram is suspected of carrying out the attacks.
