Militants from the group Boko Haram killed four people and injured two others in an attack on a village in southern Niger, a regional official said on state television late on Monday, Reuters reported. The group has sought to carve out an emirate based on a severe interpretation of Islamic law in northeastern Nigeria and has also carried out numerous attacks across the border in neighbouring countries, including Niger. Members of Boko Haram, armed with Kalashnikovs, attacked the village in the southern region of Diffa over the weekend. About 50 villagers' homes were set ablaze during the violence. "We have noted four deaths, and two other wounded people were evacuated to the hospital in Diffa," Fougou Boukar, an official for the region, said on state television. "Defence and security forces have been deployed in the area."
