Three bomb explosions have rocked Afghanistan's southern Kandahar province and gun shots have crackled in the area amid rising insecurity in the war-hit country, officials say.

There's no immediate report of possible casualties in the attacks, which reportedly targeted police headquarters in the volatile southern Afghan city of Kandahar, a Press TV correspondent reported Saturday. 

Local officials, who declined to be named, stated that firing is continuing in the city, adding that shots had been fired at the police office from a nearby hotel. 

The police headquarters has come under attacks by gunmen with AK-47 assault rifles pointing out of the windows of the building.

In a separate incident, another explosion was heard in the same area as well as further gun fires in some other parts of the city.

The security situation remains fragile throughout the war-ravaged country despite the presence of 150,000 US-led foreign forces.

In September 2010, Mohammad Hassan Timori, the provincial Director of Haj and Religious Affairs, was killed when his vehicle was hit in a bomb attack in the southern city of Kandahar.

Deputy provincial governor of Kandahar Abdul Latif Ashna was also assassinated on his way to work in the volatile city in January this year.

According to the Afghan interior ministry, more than 2,000 civilians lost their lives in violence across the country in 2010.

Hundreds of civilians have been killed in US-led airstrikes and ground operations in various parts of Afghanistan over the past few months, with Afghans becoming increasingly outraged over the seemingly endless number of deadly assaults. source
