Israel says it has killed the Iranian navy chief overseeing what is a near-total blockade of the Strait of Hormuz.

Alireza Tangsiri, head of the Islamic Revolutionary Guards Corps (IRGC) navy, was "directly responsible for the terrorist act of bombing and blocking the Strait of Hormuz", and has been "blown up", according to Israel's defence minister Israel Katz.

He added that a number of other "senior Navy command officials" have also been killed. Iran has not yet commented.

Since the start of the war on 28 February, Israel has assassinated several top Iranian officials, including Supreme Leader Ayatollah Ali Khamenei and security chief Ali Larijani.

Effectively blockading the Strait of Hormuz - the thin waterway between Iran, the United Arab Emirates (UAE) and Oman, through which around 20% of the world's oil and liquefied natural gas normally passes - has been a key pillar of Iran's strategy in the war.
