A Taliban suicide bomber targeted a Nato convoy in downtown Kabul on Sunday, triggering a powerful explosion in a rush-hour attack that comes just days after the resurgent militant group overran a key northern city, The Times of India reported.

No casualties were immediately reported from the bombing, which sent a thick plume of smoke rising into the sky, as the Taliban ramp up attacks on government and foreign targets.

Security officials cordoned off the area as ambulances with wailing sirens rushed to the scene, which was littered with the mangled wreckage of vehicles.

Taliban spokesman Zabihullah Mujahid said that they were behind the bombing.
