An Afghan official says a suicide bomber has struck near Kabul's international airport, with casualties expected.

Najib Danish, the deputy spokesman for the Interior Ministry, says the bombing happened inside the major checkpoint leading into the airport early Sunday morning.

He says one foreign vehicle and two civilian vehicles have been damaged, but casualties are not yet known. It is not yet clear whether the attacker was on foot or in a vehicle.

No one has claimed responsibility. The Taliban, which have waged war in Afghanistan for more than a decade, launched their warm weather offensive in late April.

The insurgents claimed responsibility for an attack on a Kabul guesthouse last week that left 14 people dead, including nine foreigners.
