N'Djamena (Chad), June 16: At least 27 people were killed and 100 injured in two simultaneous attacks allegedly carried out by Boko Haram in the Chadian capital N'Djamena.
Chad witnessed first such attacks after becoming western ally in fight against Islamist groups in the Sahel.
"Boko Haram is making a mistake by targeting Chad," Communications Minister Hassan Sylla Bakari was quoted as saying.
"Most of the casualties and injured were found in the police training school where a suicide bomber entered the compound and detonated his charge among a group of cadets," authorities said.
Chad, earlier a French Colony, has been with France in its counter-terrorism Operation Barkhane in the Sahel region. French army has set up its headquarters for the campaign in N'Djamena.
Boko Haram has been waging a six-year campaign of violence in northeastern Nigeria that has left at least 15,000 people dead and increasingly spilled across borders.
