The threat comes after Iran said it had identified "35 US targets" it could hit in retaliation for the killing of a top general in a US airstrike on Friday.

Qasem Soleimani, the former head of the Iranian Revolutionary Guards' elite Quds Force, was killed in a targeted drone strike as he left Baghdad Airport in a convoy with a number of other military officials.

The strike came after the US embassy in Iraqi capital Baghdad was attacked by mobs wearing the uniform of the Hashd, an umbrella group of Iranian-backed militia operating within Iraq.

Hours after the strike, rockets were again fired near the embassy and at an airbase housing American troops.

Iranian general Gholamali Abuhamzeh later said that some 35 "vital American targets", including destroyers and warships near the Persian Gulf and Tel Aviv, were "within out reach".
