LONDON, March 23 (Reuters) - A British man detained in Tehran urged Prime Minister Keir Starmer on Monday to "step out of the shadows" and publicly challenge the spying charges against him and his wife, who now fear for their lives more than three weeks into the Iran war.

Craig Foreman and his wife Lindsay were sentenced to 10 years in prison in February after Iran accused them of spying for Britain and Israel. The couple have repeatedly denied the charges.

London's police chief pledged Monday over 250 more officers and "highly visible" armed patrols to protect the Jewish community after an arson attack on four volunteer ambulances run by a Jewish organisation next to a synagogue.

The U.S. is considering plans to occupy or blockade Iran's Kharg Island, the country's main oil export hub, to pressure Tehran to reopen the Strait of Hormuz to all shipping, according to Axios.

Washington sent a peace plan to Iran, US media reported, as Donald Trump voiced optimism Tuesday at ending nearly a month of warfare and Tehran announced that it will let "non-hostile" oil vessels go through the crucial Strait of Hormuz.

The tentative signs of a diplomatic solution came despite new violence, with an Iranian missile causing injuries in Israel, which in turn pressed on multiple fronts and vowed to seize control of a strip of southern Lebanon.

BEIJING, March 23 (Reuters) - China on Monday urged all parties involved in the Middle East conflict affecting the Strait of Hormuz to end military operations to prevent a "vicious cycle" and return to negotiations.

"Should hostilities continue to escalate and the situation deteriorate further, the entire region will be plunged into chaos," the Chinese foreign ministry spokesperson Lin Jian said when responding to a question about U.S. President Donald Trump pressuring Iran to reopen the key shipping waterway.
