Kabul, Aug 20 (DPA) Several rockets hit southern and northern provinces early Thursday and police arrested two would-be suicide bombers, shortly after voting started in Afghanistan's presidential election, officials said.

Two rockets landed close to a polling station in the northern city of Kunduz, the capital of the province of the same name, Thursday morning, said Mohboobullah Sayedi, spokesman for the provincial governor.

He said no one was hurt in the attack, but a DPA reporter in the town saw a wounded child and the school which was turned into voting site was damaged.

A bomb went off near a police headquarters in the northern province of Takhar, causing no casualties but destroying the wall of the station, said Ziauddin Mahmoodi, the provincial police chief.

He said police also arrested two would-be suicide bombers, who tried to enter polling stations in the province's Farkhar district.

A district police chief for the northern province of Baghlan was killed Thursday morning when militants attacked a police post in the province, a security source in the province said.

At least two rockets also landed in the southern province of Kandahar, but caused no casualties, the provincial governor Tooryalai Wesa told reporters after casting his vote in the province.

At least two civilians were wounded when a rocket landed in Lashkargah, the capital of the southern province of Helmand, also Thursday morning, a security source who requested anonymity said.
