Death toll in Nigeria convoy attack rises to 30
Two sources told AFP the number of fatalities from the attack Friday had doubled as more bodies were found and now included 12 policemen, five soldiers, four members of a government-backed militia and nine civilians.
Earlier, sources told AFP that eight policemen, three soldiers and four members of a government-backed militia were among those killed in the attack on vehicles carrying Borno governor Babagana Umara Zulum near the town of Baga on the shores of Lake Chad.
The insurgents opened fire with machine guns and rocket-propelled grenades as the convoy was passing through a village close to the headquarters of the Multinational Joint Task Force (MNJTF), a military coalition of troops from Nigeria, Niger, Chad and Cameroon.
"The governor escaped unhurt," one source said.
Zulum was on an assessment tour of Baga in preparation for the return of thousands of residents displaced from the town by the jihadists in 2014, the sources said.
The governor flew on a helicopter into the garrison town of Monguno, 60 kilometres away, and headed to Baga in a convoy under tight security, one of the sources said. All three sources were talking on condition of anonyonimity.
The IS-affiliated Islamic State West Africa Province (ISWAP) group maintains most of its camps on islands in Lake Chad and the region is known as a bastion for the jihadists.
The militant group has recently intensified attacks on military and civilian targets in the region.
Last week the group killed a Nigerian army commander along with three soldiers in an ambush near the town of Damboa.
Civilians plying highway linking Monguno and the regional capital Maiduguri said the jihadists set up daily checkpoints, robbing, killing and abducting passengers.
The decade-long insurgency in northeast Nigeria has killed 36,000 people and forced over 2 million from their homes.
Most of the displaced have been housed into squalid camps where they depend on food handouts from international charities.
Local authorities have been encouraging the displaced to go back to the homes despite concern from aid agencies of the security risks to which the returnees would be exposed.
Last week Zulum said feeding the displaced was not financially sustainable, insisting the only option was for them to return and rebuild their homes and live a "dignified" life.
ISWAP splintered from the main Boko Haram group in 2016 and has gone on to be the dominant insurgent force in the region.
