Chinese Foreign Minister Wang Yi on Tuesday sent a message of condolence to his Russian counterpart Sergey Lavrov over the assassination of Russian Ambassador to Turkey Andrei Karlov in the Turkish capital of Ankara.

China strongly condemns the barbaric and brutal terrorist attack on the diplomat and firmly opposes terrorism of all forms, Wang said in the message.

China is willing to work with the international community in firmly supporting Russia's efforts and actions to fight terrorism, and strengthen anti-terrorism cooperation, Wang added.

Earlier on Monday, Karlov was killed by a Turkish off-duty police officer at an art exhibition ceremony in Ankara.
