Iran's foreign minister arrived in Geneva ahead of a second round of negotiations with the United States, as the Revolutionary Guards on Monday begin military drills in the strategic Strait of Hormuz.

Some residents of Tehran on Sunday chanted slogans against the clerical leadership from balconies and windows, reports said, a day after Iranians abroad staged giant opposition rallies in Europe and North America.

Israeli Prime Minister Benjamin Netanyahu said on Sunday that any deal between the United States and Iran must involve the removal of all enriched uranium from Iran as well as Tehran's ability to enrich more.

Gaza's civil defense agency reported that Israeli strikes killed at least 11 people since dawn on Sunday, while a military official said the attacks were carried out in response to violations of the ceasefire.

The exiled son of Iran's last shah said he was ready to lead the country to a "secular democratic future" at a rally in Munich on Saturday, after U.S. President Donald Trump said a change of power would be the "best thing".

The U.S. and Iran are expected to hold a second round of nuclear talks in Geneva next Tuesday in an effort to reach a deal that prevents war, a U.S. official and three sources with knowledge told U.S. news portal Axios.

With one American carrier strike group already in the Middle East and another apparently on its way as U.S. President Donald Trump ramps up pressure on Iran to give up its nuclear program, fears are rising of the outbreak of another war that could spread into a regional conflict.

The United States Central Command said on Friday it had completed the transfer of detained Islamic State group suspects held in Syria to Iraq.

CENTCOM said it "completed a transfer mission following a nighttime flight from northeastern Syria to Iraq on Feb 12 to help ensure ISIS detainees remain secure in detention facilities."

Indonesia has begun training a contingent of up to 8,000 soldiers it plans to send as part of an international peacekeeping force to Gaza, the first firm commitment to a critical element of U.S. President Donald Trump's postwar reconstruction plan.
