KABUL, Afghanistan (AP) — A United Nations vehicle was targeted in a bombing Sunday in the Afghan capital and initial reports indicated at least one foreign citizen was killed, an Afghan official said.

Nasrat Rahimi, Interior Ministry spokesman, said five others, including two Afghan U.N. workers, were wounded in the attack. The vehicle was heavily damaged.

The blast targeted the vehicle on one of the busiest roads in the city, in police district 9, according to Rahimi.

No one immediately claimed responsibility for the attack, but both Taliban and the Islamic State group are active in the capital and have repeatedly claimed pervious attacks.

In a separate report form central Daykundi Province, at least eight army soldiers were killed when Taliban stormed their checkpoint, said provincial governor, Anwar Rahmati.

Rahmati said that four other soldiers were also wounded in the hours-long gunbattle.

He said reinforcements were dispatched early Sunday to the area in Kajran district, driving off the Taliban and killing at least 20 of their fighters.

Qari Yusouf Ahmadi, a Taliban spokesman, claimed responsibility for the checkpoint attack. He disputed the Taliban casualty figures provided by the governor, and said the insurgents had seized weapons and ammunition.

The Taliban control or hold sway over half of Afghanistan, staging near-daily attacks that target Afghan forces and government officials across the country.
