Suspected Taleban militants killed at least 11 Afghans and a Philippine engineer in a series of attacks in Afghanistan Wednesday.

In one incident, insurgents ambushed a police convoy along a major highway in the southern province of Zabul, killing six officers.

Also Wednesday, two suicide bombers tried to storm the main police station in the southeastern town of Khost. Afghan officials say one of the bombers exploded himself, killing three Afghan officers. The second attacker was shot dead by police.

A suicide bomber also blew himself up near a Turkish diplomatic convoy on the outskirts of the capital, Kabul. Officials say the convoy came under small arms fire after the blast, wounding a Turkish guard. No other casualties were reported.

In other violence, a Philippine engineer died in a rebel attack on a road construction crew in the southeastern province of Paktia.

Elsewhere, officials say at least two Afghans were killed by insurgents in the eastern province of Logar.
