Tensions between the United States and Iran escalated on Monday following US President Donald Trump's announcement of a 'naval blockade' in the Strait of Hormuz.
The move prompted a sharp response from Iranian authorities, who warned of consequences if US forces approached the waterway.
Iran's Islamic Revolutionary Guard Corps (IRGC) said any US military vessel entering the area would be treated as a violation of the ceasefire and would be dealt with 'harshly and decisively'.
The force also stated that Iran maintains full control over the strait and warned that any 'wrong move' could have serious consequences, Press TV reported.
Meanwhile, the United States Navy has at least 15 ships deployed in the Middle East, including the aircraft carrier USS Abraham Lincoln and 11 destroyers, a US official said, according to CNN.
Iran's navy chief Shahram Irani described the US move as 'ridiculous and funny', while the foreign ministry criticised the blockade.
China called for an immediate end to hostilities, while US allies in NATO did not support the blockade plan.
