QALAT, Afghanistan, Oct. 14 (Xinhua) -- At least eight Afghan police personnel, including a district police chief, were killed in clashes in southern province of Zabul overnight, a provincial source said Sunday.
In one incident, police chief of Mizan district Asad Khan was killed during clashes following a Taliban attack on district's government offices and surrounding security checkpoints late Saturday night, the source said anonymously.
In neighboring Shahr-i-Safa locality, seven police officers were killed in a similar incident as they repulsed a Taliban attack on police security checkpoints.
Several militants were also killed and injured during the clashes, the source said.
Zabiullah Mujahid, a purported Taliban spokesman, has claimed responsibility for the attacks, saying three Taliban fighters were wounded in the fighting.
