Spokesman Stephane Dujarric quoted the UN Secretary-General as saying those responsible for such crimes must be swiftly brought to justice.

European Union's High Representative for Foreign Affairs and Security Policy Federica Mogherini extended her deepest condolences to the families of the victims and said the attacks are a disregard for international humanitarian law.

Twin suicide blasts, claimed by the ISIS, in the Afghan capital Kabul on Monday killed 25 people, including 10 journalists, and injured nearly 50 others. In a third attack, 11 children were killed and 16 people wounded, including foreign and Afghan security force members, when a suicide attacker exploded his bomb-laden car near a convoy in the southern province of Kandahar.
