US President Donald Trump has announced the reimposition of a blockade on Iranian ports in the Strait of Hormuz, marking a significant escalation in geopolitical tensions.

The statement, posted on Truth Social, signals a hardening of the US stance toward Iran and raises immediate concerns about the security of one of the world's most critical energy chokepoints.

The Strait of Hormuz is a vital artery for global oil and gas trade, with approximately 20% of the world's oil consumption passing through the narrow waterway.

The move comes amid heightened risks for global shipping and energy markets.
