India’s Ministry of External Affairs said it called in the Ambassador of the Islamic Republic of Iran in New Delhi after an incident in the Strait of Hormuz.

“During the meeting, the Foreign Secretary conveyed India’s deep concern at the shooting incident earlier today involving two Indian-flagged ships in the Strait of Hormuz,” the statement from India said.

“The statement noted the importance that India attached to the safety of merchant shipping and mariners and recalled that Iran had earlier facilitated the safe passage of several ships bound for India.”

“Reiterating his concern at this serious incident of firing on merchant ships, the Foreign Secretary urged the Ambassador to convey India’s views to the authorities in Iran and resume at the earliest the process of facilitating India-bound ships across the Strait.”

The UK Maritime Trade Operations reported on the second attack on a vessel near the Strait of Hormuz on Saturday, hours after Iran announced it was closing the strategic waterway yet again, dw.com reports.

UKMTO said an unknown projectile hit the container vessel 25 nautical miles (46 kilometers) northeast of Oman, damaging some of its containers.

Earlier on Saturday, UKMTO reported that two gunboats from Iran’s Revolutionary Guard opened fire on a tanker transiting the strait.

UKMTO minutes later reported on a third incident 3 nautical miles east of Oman.

“The master of a cruise ship reported sighting a splash in close proximity of the vessel,” UKMTO said.

Meanwhile, Iran’s top national security body said Saturday that the country was reviewing “new proposals” put forward by the US in recent days.

It stressed that Tehran would defend its interests and not make any compromises.

Iran’s negotiating delegation “will not make even the slightest compromise, retreat or leniency, and will defend with all its strength the interests of the Iranian nation,” the Supreme National Security Council said in a statement.

US President Donald Trump on Saturday warned Iran not to “blackmail” Washington by shutting the Strait of Hormuz once again.

“We’re talking to them. They wanted to close up the strait again, you know, as they’ve been doing for years. and they can’t blackmail us,” Trump said at a White House event.

His statement came after Tehran had earlier announced the closure of the strategic waterway, which connects the Persian Gulf to world markets and is key to global energy security, saying that the US’ continued blockade of Iranian ports and shipping violates the terms of the truce agreement reached by the warring parties.
