A bomb targeted Afghan presidential candidate Abdullah Abdullah’s convoy on Friday as he was going to a campaign rally, police said.

Two bombs exploded close to convoy vehicles in the Kote Sangi neighbourhood in western Kabul, said a police official.

He said the incident caused casualties but the number was not clear.

“On my way to a rally in Kote Sangi area, a roadside bomb hit our convoy. I am safe and nobody has been hurt,” Mr. Abdullah said in a televised rally.
