Story highlights U.S. Embassy: The Kabul attack, claimed by the Taliban, shows "blatant disregard for human life"

Official: One Afghan is killed and 22 injured in a blast targeting a foreign convoy in Kabul

A woman is among two people killed in a separate bombing in Helmand province, official says

Kabul, Afghanistan (CNN) A bombing targeted an international convoy in the Afghan capital, Kabul, on Tuesday, only hours after a deadly suicide blast rocked a city in southern Helmand province.

The Kabul suicide car bomb targeted the foreign forces as they traveled along the airport road, Afghan Interior Ministry spokesman Sediq Sediqqi said.

One Afghan civilian was killed and 22 other civilians were wounded, Sediqqi said.

Dr. Kabir Amiri, head of Kabul's Central Hospital, said 17 injured people, including three children and a woman, were taken to different hospitals in the city after the attack.

The blast caused smoke to rise above the city and triggered an alarm in the U.S. Embassy. The road runs close to the embassy and other diplomatic compounds in Kabul.
