Kabul, July 26 (DPA) Militants using machine guns and rocket-propelled grenades attacked one of President Hamid Karzai's running mates in northern Afghanistan Sunday, but caused no casualties, the provincial governor said.

Mohammad Qasim Fahim was travelling in a convoy in Khan Abad district of Kunduz province Sunday afternoon, when he was ambushed, provincial Governor Mohammad Omar told DPA.

Fahim, who was campaigning on Karzai's behalf in the northern provinces, was heading towards neighbouring Takhar province on a highway when militants 'fired rockets and machine guns from the other side of the river', Omar said.

'Thank God nobody was hurt in the attack and the convoy just continued on its way,' he said, adding that the area from where the attack was launched was not fully manned by Afghan security forces.

'Taliban are active in this are,' he said.
