Two groups of suicide bombers targeted a market and a refugee camp in Chad, killing at least 38 people.
Authorities suspect the extremist Boko Haram group from neighbouring Nigeria staged the attacks in the western village of Baga Sola.
Female suicide bombers hit the market in Baga Sola when it was at its busiest on Saturday, killing at least 16 people. Other suicide bombers killed at least 22 people at the nearby refugee camp.
For months, Baga Sola has been home to thousands of people who already had fled deadly Boko Haram attacks in Nigeria. The village is in the Lake Chad region near the border with Nigeria.
While Boko Haram has attacked Chad’s capital before, these bombings appear to be the largest yet in the country’s lake region. The extremists have stepped up attacks in Nigeria and neighbouring Niger, Cameroon and Chad.
