8 killed in attack on foreign camp in eastern Kabul

"There were at least two suicide car bombing near a logistic camp named Green Village run by foreigners in Pul-i-Charkhi area this morning," a police source told Xinhua.

He said the killed include a foreign security guard, five civilians and two suicide bombers.

The attacks came hours after U.S. President Barack Obama left Kabul following a surprise visit, during which he signed the strategic partnership agreement with his Afghan counterpart Hamid Karzai.

The attack occurred at about 6:15 a.m. local time and Taliban insurgents claimed the responsibility for the attack.

At least 17 people were injured in the attack, a health official in Wazir Akbar Khan hospital told Xinhua, adding some of the injured were school children.

A Xinhua reporter near the site said that sporadic firing still could be heard in the area.

The area was cordoned off by security forces and police were on high alert across the Kabul while several helicopters were hovering above the area to monitor the situation.
