US President Donald Trump has vowed to avenge the deaths of three American soldiers killed during operations against Iran, while warning that more casualties were likely.
The US president also called on Iranians to rise up, saying "America is with you," and warned the country's Revolutionary Guards to surrender or face "certain death."
Trump said he envisaged a four-week military operation against Iran, where US and Israeli strikes have killed the country's supreme leader and crippled its defense capabilities.
"It's always been a four-week process. We figured it will be four weeks or so," he told British newspaper the Daily Mail during a round of interviews.
"As strong as it is, it's a big country, it'll take four weeks -- or less," Trump said.
A senior White House official says that “new potential leadership” in Iran has suggested they are open for talks with the United States. The official, speaking on condition of anonymity to discuss internal administration deliberations, said Trump says he is “eventually” willing to talk, but for now the military operation “continues unabated.”
