Iraq is exerting "maximum effort" to prevent any escalation on its territory, the foreign ministry said, after the US embassy in Baghdad warned of possible attacks in the city by pro-Iran armed groups.

Around 40 countries called for the immediate reopening of the Strait of Hormuz, Britain's foreign minister said.

"Iran is trying to hold the global economy hostage in the Strait of Hormuz. They must not prevail.

- China condemns -

China's foreign minister Wang Yi said US and Israeli attacks on Iran were a violation of international law, Chinese state media reported, as he held calls with his EU, German and Saudi counterparts.

Wang also said the UN Security Council -- of which China is a permanent member -- "should prevent the escalation of conflict", state broadcaster CCTV said, as the international body debates a draft resolution on the use of force in the Strait of Hormuz.
