An Iranian tanker caught in a standoff between Tehran and the West was sailing to Greece on Monday after leaving Gibraltar, and Iran warned against any U.S. move to seize the vessel after the British territory rejected a U.S. request to detain it.
Iran's foreign ministry said a U.S. attempt to seize the oil tanker would have "heavy consequences" and a senior Iranian lawmaker said
the crisis with Britain would only end after the vessel reached its destination.
British Royal Marines seized the tanker near Gibraltar in July on suspicion it was carrying oil to Syria, a close ally of Iran, in violation of European Union sanctions. That led to heightened tensions on international oil shipping routes through the Gulf.
