China’s Foreign Minister Wang Yi has told his Russian counterpart Sergei Lavrov that attacks by the United States and Israel on Iran during US-Iran negotiations were “unacceptable”, according to state news agency Xinhua, AFP reports.

Wang said the “blatant killing of a sovereign leader” and the incitement of regime change were unacceptable, after Iran reported the death of Supreme Leader Ali Khamenei in Saturday’s barrage.

China is calling for an immediate cessation of military action, a return to dialogue and negotiations as soon as possible, and joint opposition to unilateral actions, the minister said.
