N’DJAMENA, Chad — At least five suicide bombers Saturday targeted a village in Chad that is home to thousands of Nigerians who have fled Islamic extremist violence, killing at least 36 people and wounding about 50 others in what appeared to be coordinated attacks, officials said.

Authorities blamed the extremist Boko Haram group from neighboring Nigeria for staging the attacks in the western village of Baga Sola, according to a government spokesman. He said 41 people had died, including the five suicide bombers who were identified as two women, two children and a man.

Female suicide bombers hit the market in Baga Sola when it was at its busiest Saturday, killing at least 16 people, said the director general of Chad’s gendarmerie. A second group of suicide bombers killed at least 22 people at a refugee camp, he said.
