TEHRAN - Iran strongly condemned a deadly attack on a restaurant in the Afghan capital Kabul, which left at least 21 people dead on Friday, Press TV reported Sunday.

Gun and bomb attack in Kabul was aimed at destabilizing Afghanistan, Iranian Foreign Ministry Spokeswoman Marzieh Afkham was quoted as saying.

The purpose of such acts of violence and terrorism in Afghanistan is to disrupt stability and security in the country, Afkham said.

She also expressed confidence that the unity between the Afghan people and the government can weather the sensitive circumstances in the country.

The Taliban claimed responsibility for the attack on the La Taverna du Liban restaurant owned by Lebanese national Kamal Hamade, who also lost his life in the offensive.
