At least 30 people were killed in a double suicide bomb attack in Kerawa in the Far North region of northern Cameroon on Thursday, AFP reported. Boko Haram militants had targeted the region last February.

Local reports claimed on social media that at least 100 people were injured.

"The first (explosion) was just after 9 o'clock (0800 GMT) in the market in Kerawa and the other one was around 200 metres (yards) from the (military) infantry camp," an army officer based in the north told Reuters.

According to  Cameroonweb.com, minutes after the first blast, a woman posing as injured approached the clinic  belonging to  special rapid intervention battalion (BIR) and blew herself up.

In July, at least 13 people were killed and several others injured in twin suicide attacks suspected to have been carried out by Boko Haram militants in Maroua, also in Far North Region.

Female suicide bombers were believed to have been used by Boko Haram for the deadly attack.

More details awaited.
