UN leader Ban Ki-moon on Friday strongly condemned a suicide gun and bomb attack on a Kabul restaurant in which three UN staff were among at least 14 fatalities.

A UN statement said other dead from the attack claimed by the Taliban were from international organisations.

“Such targeted attacks against civilians are completely unacceptable and are in flagrant breach of international humanitarian law,” Ban was quoted as saying by a spokesman.

Ban condemned the attack “in the strongest terms,” said deputy UN spokesman Farhan Haq.

“Three United Nations personnel, along with a number of those from other international organisations, are now confirmed dead,” added Haq.
