(CNN)—The US Central Command (CENTCOM) on Saturday described the Iranian Revolutionary Guard's announcement of 'two oil tankers exploding after hitting mines' in the Strait of Hormuz as a 'baseless claim.'

CENTCOM said on platform 'X' (formerly Twitter): 'The claim: The Iranian Revolutionary Guard claims that two oil tankers exploded in the Strait of Hormuz after hitting mines in the international waterway. But the truth is that this claim, like most Revolutionary Guard claims, is baseless.'

Iran's official news agency reported earlier Saturday, citing the Revolutionary Guard, that two oil tankers had exploded and caught fire after attempting to cross a mined path in the Strait of Hormuz.

In a statement, the Guard described the waterway as having become 'extremely unsafe and completely closed.'

CNN cannot independently verify the Iranian claims.

Six ships crossed the Strait of Hormuz in the past 24 hours according to 'MarineTraffic' data, reflecting the increasing pressure on vessels in one of the world's busiest sea lanes.

These included one tanker and two cargo ships leaving the strait, and two tankers and one cargo ship entering it; these numbers align with transit rates recorded in recent days, which have seen a decline.

Earlier this month, US President Donald Trump announced a plan to impose a 20% fee on all cargo shipments passing through this waterway, adding an additional burden on shipping traffic in the region.

Since the outbreak of the war, the strait has also seen an increase in GPS signal manipulation—a form of jamming that shows ships at incorrect coordinates—although this phenomenon had subsided before the breakdown of talks between the US and Iran earlier this month.
