A US citizen was killed and another was injured in a shooting attack that targeted US embassy annex in Kabul, late on Sunday.

The attack was carried by an Afghan employee inside the Ariana Hotel compound, an annex to the US embassy in the Afghan capital, the embassy said on Monday.

"There was a shooting incident at an annex of the US embassy in Kabul involving an Afghan employee who was killed," said US embassy spokesman Gavin Sundwall. "One US citizen was killed, one was wounded."

According to news reports and official sources, the building is believed to include a major CIA office for Afghanistan.
Analysts say some groups in Afghanistan want to derail NATO's plans to handover security responsibility to Afghan forces by 2014.

In this context, NATO's secretary-general, Anders Fogh Rasmussen, recently told reporters: "We are witnessing that the Taliban try to test transition but they can't stop it. Transition is on track and it will continue."

Kabul, at one time considered a relatively secure area, has witnessed several recent attacks.
Last week, Burhanuddin Rabbani, Afghanistan's former president who headed a team tasked with negotiating peace with the Taliban, was killed in a suicide attack on his home.

Two weeks ago, fighters launched an assault against the US embassy and NATO headquarters in Kabul.
