Nigeria’s Islamist militant group Boko Haram has carried out two cross-border attacks into Cameroon since Friday, killing at least four soldiers and prompting the Cameroonian army to send reinforcements to the area, army sources said on Saturday.

Under pressure from neighboring Nigeria to do more to counter Islamist insurgents, Cameroon has deployed over 1,000 soldiers along its remote jungle border.

Nigeria believes Boko Haram wants to use Cameroon as a rear base as it strives to carve out an Islamic state. The group has killed thousands in its five-year insurgency and has recently bombed targets that were previously considered comparatively safe, such as Nigeria’s commercial hub Lagos and capital Abuja.

Cameroonian regional military commander Colonel Felix Nji Formekong confirmed to Reuters by telephone that four soldiers had been killed in clashes with Boko Haram fighters at the village of Bargaram, without giving further detail.
