In a statement issued Wednesday by his Spokesman Stéphane Dujarric, the Secretary-General expressed his deep sympathy to the families of the victims.

According to initial reports, the attack on the offices of Save the Children in Jalalabad killed two people and wounded dozens, including children.

“Humanitarian organizations provide life-saving assistance to the most vulnerable men, women and children in Afghanistan. Aid workers, and their premises and assets, should never be a target,” the statement said.

“The Secretary-General reiterates that all parties to the conflict in Afghanistan are obliged under international law to protect humanitarian workers and civilians,” it added.
