United Nations chief Antonio Guterres has strongly condemned the suicide attack in Afghanistan’s Jalalabad city that killed 19 people, mostly Sikhs and Hindus.

The UN chief said in a statement issued by his spokesperson that any attack targeting civilians is unjustifiable and in clear violation of international law.

The UN Secretary-General expressed his condolences to the families of the victims and urged all parties to uphold their obligation to protect civilians, including minority communities.

The majority of victims belong to Afghanistan’s small Sikh and Hindu community. The Secretary-General extends his deepest condolences to the families of the victims and wishes a speedy recovery to those injured.

An ISIS suicide bomber targeted a convoy of Sikhs and Hindus on their way to meet the Afghan president Ashraf Ghani in the eastern city of Jalalabad on Sunday.
