Nigeria was shaken on Sunday by a series of attacks on Catholic churches, making nearly thirty dead and several wounded.
The first explosion claimed by the Islamic sect Boko Haram occurred in the Catholic Church of St. Theresa-Madalla, near the capital Abuja. The provisional toll is at least 28 dead, according to rescuers.
Chaos reigned around the building after the explosion. Angry youths lit fires and threatened to attack a police station nearby. The police fired into the air to disperse them and closed access to a major road.
Another explosion occurred in a church in the city of Gadaka, north-east, injuring several people. Then, a third attack took place near a church in the city of Jos in central Nigeria. At least one death was reported.
In mid-December, leaflets threatening attacks against churches and other places in Jos had circulated,they enumerated 21 targets.
Jos, located in the middle-belt region of the predominantly Muslim north and predominantly Christian south of Nigeria, is regularly the scene of ethnic violence, religious and economic.
In December 2010, Jos was rocked by bombings claimed by the Islamic sect Boko Haram.These attacks resulted in the death of 80 people.
Sunday's explosion occurred a few days after a series of deadly attacks in the north-east, also claimed by the group Boko Haram.
