In two operations, a multinational group police the turbulent Lake Chad basin announced it had killed more than 30 ‘jihadists.’

The Multinational Joint Task Force (MNJTF) said ground and air attacks in the Tumbun Rago area in the northeastern Nigerian state of Borno had “neutralized more than 25 terrorists”.

Five more were killed in Kirta Wulgo, also in Borno state, it said in a statement.

“Terrorists” is a term the MNJTF customarily uses for jihadists.

Seven soldiers from Chad and Niger were slightly wounded, it said.

The operations were carried out last week under an offensive called Operation Lake Integrity, which was launched on March 21, an officer at the force’s headquarters in the Chadian capital N’Djamena told AFP.

The southwestern fringe of Lake Chad has become a haven for jihadists from Nigeria’s Boko Haram and its rival, the Islamic State West Africa Province (ISWAP), who hide on islands in its vast marshlands

In 2015, the four countries bordering the lake — Chad, Cameroon, Niger and Nigeria — joined with Benin to reactivate the MNJTF, which was set up in 1994 but had been largely dormant.

The MNJTF said in early May that around 20 ‘terrorists’ had been killed in the Lake Chad area.

Attacks in the Lake Chad area originated with the rise of Boko Haram in Nigeria in 2009.

According to UN data, more than 36,000 people have died since then, the majority of them in Nigeria, and approximately three million have fled their homes.
