Iran has reimposed 'strict control' on the Strait of Hormuz, reversing a decision to unblock the strategic waterway amid a row with the US over a naval blockade.
The move comes after US President Donald Trump said the blockade 'will remain in full force' until Tehran reaches a deal with Washington, including on its nuclear program.
The US has deployed forces and initiated a blockade on Iranian ports as part of an effort to force Tehran to accept a ceasefire.
Control over the Strait of Hormuz is key for Iran, with roughly one-fifth of the world's oil passing through the waterway.
The conflict over the chokepoint threatens to deepen the energy crisis roiling the global economy, with oil prices falling amid hopes of a US-Iran agreement.
