China on Thursday condemned the twin bombings that hit the Lebanese capital Beirut, which killed at least 6 people and injured 129 others.

"China strongly condemns the terrorist attacks and is firmly against all forms of terrorism," Chinese Foreign Ministry spokeswoman Hua Chunying told a routine news briefing.

China supports the Lebanese side in safeguarding its peace and stability, Hua said, urging all parties to serve the same aim.

A suicide bomber on Wednesday blew up a car in the southern suburbs of Beirut, just moments before another suicide bomber riding a motorcycle set off a bomb in a crowd of people.

The attacks were later claimed by Al-Qaida-linked Abdullah Azzam Brigades "in retaliation to Hezbollah and Tehran's role in the Syrian war."
