Tensions in the Middle East escalated on Tuesday as Iran issued strong military threats against the US and Israel, warning nearby Gulf countries of severe consequences.
US Vice President JD Vance's planned trip to Islamabad for peace talks with Iranian officials has been cancelled, according to a White House official.
President Donald Trump extended the current ceasefire with Iran, awaiting a 'unified proposal' from the Iranian government.
Mojtaba Khamenei, Iran's supreme leader, posted a warning on Telegram about possible drone and missile attacks on the US and Israel.
The warning comes as the US blocks Iranian ships after Iran closed the Strait of Hormuz, and planned peace talks in Islamabad have yet to begin.
Iran's Revolutionary Guards also issued a warning to Gulf neighbors, threatening to halt oil production in the Middle East if their territory is used to stage attacks against Iran.
