Nine people, including four foreigners and two children, have been killed in a gun attack at a luxury hotel in Kabul, Afghan officials said today.

They said the gunmen took a few minutes to find the restaurant where last night's shootings took place.

Interior Ministry spokesman Sediq Sediqqi said the attackers reached the hotel at 8.30pm local time, evading security checks by hiding small pistols and ammunition in their socks and the soles of their shoes.

He told reporters today that some details about the attack have changed as authorities piece together the events.

He said five Afghans were among those killed, including two children who were shot in the head. The foreign victims were from Canada, New Zealand, India and Pakistan.

Yesterday's attack is the latest targeting foreigners in the Afghan capital.
