DOHA, June 17 (Xinhua) -- Qatar strongly condemned the terrorist attack that took place in the Nangarhar Province in eastern Afghanistan during a cease-fire ceremony, said state-run Qatar News Agency (QNA) on Sunday.

In the attack, at least 26 people were killed and 54 injured.

In a statement, the Ministry of Foreign Affairs expressed Qatar's full solidarity with the Afghan government and its support for all efforts in achieving peace and stability in Afghanistan, QNA said.

Qatar also considered the attack as an attempt to deter the cease-fire agreement between the Afghan government and the Taliban movement.

Qatar also sent its condolences to the families of the victims, the government and the people of Afghanistan, the statement added.

On Saturday afternoon, Nangarhar witnessed an explosion during one of the cease-fire celebrations between the government and the Taliban.

The Islamic State militant group said it carried out the attack.
