China strongly condemns the attack against diplomatic missions and personnel, Chinese Foreign Ministry spokesperson Mao Ning said on Tuesday. She made the remarks in response to the bombing attack outside the Russian embassy in Kabul, Afghanistan. 

At least six people, including two Russian embassy staff, were killed, and 15 others were injured in the suicide bombing near the embassy's entrance, the Russian Foreign Ministry and Afghanistan officials said on Monday. 

China urges the Afghan side to take effective measures to ensure the security of foreign diplomatic missions and personnel in Afghanistan, Mao said, adding that the international community should work together to play a constructive role in maintaining peace, stability and security in Afghanistan.
