A bomb exploded next to a vegetable market in eastern Afghanistan early Saturday, killing two people, police and hospital officials said.
At least 16 others were wounded, said Dr Abdul Raman Shan, who was treating the injured at a local hospital.
Yaqoob Khan, the deputy police chief for Khost province, said the bomb exploded on a road just outside the market and appeared to be targeting a nearby vehicle belonging to a private security company. Khan said he did not know if anyone in the vehicle was injured. The attack comes a day after Afghan and coalition forces killed an Afghan civilian in the same province.
US forces spokesman Col. Greg Julian said the troops fired warning shots toward a vehicle that was "driving erratically" and did not respond to their signals. The injured civilian later sought treatment at a coalition medical facility, but died. "We regret this tragic loss of life and express our condolences to the individual's family," Julian said in a statement. Also Friday, Afghan and coalition troops killed four militants in western Farah province during a raid on a compound associated with a Taliban commander, U.S. forces said in a statement. The statement said local residents confirmed that those who died in the ensuing firefight were Taliban militants.
Separately, U.S. forces said coalition troops detained three suspected militants during a search of a compound connected to a local Taliban commander in Ghazni province on Friday, according to a statement.
This followed a clash Thursday near a main road in southern Helmand province in which Afghan and coalition troops were attacked while on patrol and returned fire, killing 10 militants, U.S. forces said in a statement.
