At least 27 people were killed and more than 80 wounded Saturday in a triple suicide bombing on an island in Lake Chad, a security source said in the capital N'Djamena, reports AFP. "Three suicide bombers blew themselves up in three different places at the weekly market on Loulou Fou, an island in Lake Chad," the source told AFP, speaking on condition of anonymity. He said the explosions had "killed 30 people", including the attackers, and wounded more than 80. N'Djamena on November 9 declared a state of emergency in the flashpoint Lake Chad region, which also straddles Nigeria, Cameroon and Niger and is frequently targeted by Boko Haram Islamists who this year declared allegiance to the Islamic State.
