BEIJING: China called on Monday for a ceasefire and diplomatic talks to end the conflict in the Middle East as it stretched into a third day.

Israel and the United States have been conducting strikes on Iran and Lebanon, with the conflict extending to regional neighbours.

"The most urgent task is an immediate cessation of military operations and preventing a spread and spillover of conflict," foreign ministry spokeswoman Mao Ning told a news conference, urging "a resolution through dialogue and negotiation".

One Chinese citizen was killed as a result of the conflict in Tehran, she said, where Israel and the United States have been carrying out strikes in an operation that killed the Islamic republic's supreme leader.

"The foreign ministry has instructed the Chinese embassy in Iran to provide assistance to the individual involved and the family," Mao added, without giving further details of the victim or incident.
