BAMAKO, MALI —
The U.N. says five Chadian peacekeepers have been killed and three wounded after being attacked in northern Mali.
A statement from the U.N. secretary-general's spokesman says the peacekeepers' convoy hit a roadside bomb and then came under fire from gunmen.
The attack took place Wednesday about 9 miles (15 kilometers) north of Aguelhok in the northern Kidal region. Seven other peacekeepers have been killed there so far this year.
U.N. Secretary-General Ban Ki-moon called it a "heinous attack'' and noted it would be considered a war crime under international law.
Islamic extremists have been attacking international peacekeepers and Malian soldiers working to stabilize the north three years after a French-led military campaign ousted jihadis from power.
