"We have a provisional toll of 10 dead, four missing and three wounded," defense ministry spokesman Abdoul-Aziz Toure told AFP, nearly a month after the last attacks attributed to the group killed six, shattering several months of calm in the troubled region.
The attack by Boko Haram had targeted Niger’s "army positions in Bla Brin, a village not far from the Lake Chad area, 40 km (25 miles) from the town of N’Guigmi," he added.
The last attacks attributed to Boko Haram took place in early June.
Three suicide bombers killed at least six people in separate attacks in the southeastern Niger city of Diffa.
In late April, Niamey announced a military operation against Boko Haram in the region of Lake Chad, which links Niger, Chad, Nigeria and Cameroon.
The group, which is seeking an Islamic state based on Sharia law, has caused the deaths of at least 20,000 people since it took up arms in 2009 in Nigeria.
Some 2.4 million people have been displaced in northern Nigeria, Cameroon, Chad and Niger, according to the U.N. refugee agency UNHCR.--AFP
