Afghan locals inspect the site of a bomb attack in Herat, August 15, 2012.
At least two security personnel have been killed and five others injured in a bomb attack near a police station in the western Afghan province of Herat, Press TV reports.
The bombing on Wednesday was carried out at 6:30 a.m. local time in a police parking lot in the Adraskan district of the province, located about 640 kilometers (396 miles) west of the capital, Kabul, said Abdolraouf Ahmadi, a local police spokesman.
No group has claimed responsibility for the attack, but similar incidents are usually blamed on the Taliban militants.
On Tuesday, 12 people, including South Africans, were killed in a car bomb attack targeting a vehicle carrying foreigners to Kabul International Airport.
Violence in Afghanistan has been on the rise in recent months despite the presence of thousands of US-led foreign forces in the war-weary country.
The United States and its allies invaded Afghanistan in 2001 as part of Washington’s so-called war on terror.
The offensive removed the Taliban from power, but years into the invasion, insecurity continues to rise across the country.
