Chadian army has been on the front line of a regional military operation against Boko Haram as attacks spread.
Female bombers blew themselves up and killed at least 15 others on an island in Lake Chad with security officials accusing the armed group Boko Haram of carrying out the deadly assault.
More than 130 people were also wounded in the attacks by at least three young women on a busy market on Saturday on the island of Koulfoua on the Chadian side of Lake Chad.
“The provisional death toll is 19 dead, including the four kamikazes, and 130 injured,” state TV reported.
Two of the blasts rang out from the centre of the market and a third in the street as people fled, security sources said.
No one claimed responsibility for the attacks, but officials pointed fingers at the armed group Boko Haram from neighbouring Nigeria.
General Banyaman Cossingar, Chad gendarmerie director general, confirmed the attack saying Boko Haram is suspected, the AP news agency reported.
Chad’s government instituted a state of emergency in the Lake Chad region last month, saying the area had become a gathering point for Boko Haram fighters.
More than 5,000 soldiers have been deployed on islands and lakeside villages there.
Earlier this year, thousands of people fleeing Boko Haram sought refuge on the island although it was not immediately clear if they were still based there.
Boko Haram, which has led a six-year armed campaign in Nigeria, has stepped up attacks this year in Chad, Niger, and Cameroon after those countries agreed to fight the group. An estimated 20,000 people have been killed.
