UN Secretary-General Antonio Guterres on Wednesday condemned the alleged use of nerve agent in the poisoning of a former Russian spy in Britain.
"The secretary-general is deeply concerned over the reported use of a nerve agent in the United Kingdom to harm or kill persons," said Farhan Haq, Guterres' deputy spokesman.
"The use of nerve agents as a weapon under any circumstances is unacceptable and its use by a state will constitute a serious violation of international law," Haq said.
"While the secretary-general is not in a position to attribute responsibility, he strongly condemns the use of any nerve agent or chemical weapons and hopes the incident will be thoroughly investigated," Haq told a daily press briefing.
