Iran threatens to block maritime commerce after US naval blockade of Iranian ports

Iran has formally threatened to block all maritime commerce through the Persian Gulf, Gulf of Oman, and Red Sea in response to a US-imposed naval blockade on Iranian ports. The commander of Iran's Khatam al-Anbia headquarters, Major-General Ali Abdollahi, stated on April 15 that Iran would take decisive measures to defend its sovereignty, describing US actions as illegal and aggressive.
The naval blockade by the United States targets shipping traffic to and from Iranian ports via the Strait of Hormuz, a critical chokepoint through which roughly 20% of global oil trade passes. Iran further warned that blocking the Strait of Bab el-Mandeb in the Red Sea, which handles about 5% of oil shipping, would worsen global energy market tensions.
Iran regards the US blockade as a violation of its sovereign right to trade and asserts that Washington seeks to pressure Tehran into concessions. The US government, led by President Donald Trump, aims to restrict Iranian maritime commerce to leverage negotiations.
On the diplomatic front, Pakistan's Chief of Army Staff, Marshal Asim Munir, visited Tehran on April 15 to deliver messages from the US and plan another round of talks after previous negotiations stalled. He met with Iran's Foreign Minister Abbas Araqchi as Washington signals intentions to resume talks.
Iran is also advocating for a ceasefire in Lebanon amid ongoing hostilities between Israel and Hezbollah, linking progress in the Lebanon conflict to the fragile ceasefire status between the US and Iran. Iranian officials allege Israel is violating the ceasefire agreement with US backing.
The Iranian Foreign Ministry reaffirmed its commitment to its peaceful nuclear program despite ongoing diplomatic tensions, emphasizing that it will not abandon these activities. Iranian officials continue to blame the US for failed talks due to what they call excessive demands and bad faith.
This escalation of maritime threats and stalled diplomacy indicates rising instability in a region that is vital to global energy supplies and international security.
