KABUL- After months of relative calm in Afghanistan’s capital city, Kabul was rocked today by an explosion at a supermarket popular with Americans and other foreigners working in Afghanistan.

The powerful blast killed at least 8 people including three western women who were shopping in the store at the time and injured six.

Finest Supermarket is located across the street from the British Embassy and sits at the entrance of Wazir Akbar Khan, a popular neighborhood with diplomats, journalist and other foreigners.

The entire first floor of the newly renovated grocery store was destroyed.

Afghan police say there was only one explosion, however, several witnesses say they heard an additional explosion and there appeared to be a second blast sight down the street.

While violence has hit record levels across Afghanistan, today’s attack comes after months of relative calm in the Afghan capital.

In 2009, Kabul saw a series of attacked on both military and civilian targets.

The Taliban claimed responsibility and said that insurgents were targeting the head of the “Blackwater security company in Afghanistan.”

Afghan Authorities have yet to release the names those killed or injured and could not confirm that anyone from security company, now known as Xe Services, was shopping at the store at the time of the blast.

In recent months, U.S. and ISAF officials have touted improved security in Kabul. This latest blast is a stern reminder that security situation is fragile.
