An Indian crude oil tanker carrying about two million barrels of oil from Iraq was fired upon by Iranian forces on Saturday in the Strait of Hormuz, the Hindustan Times reported.

The development came after reports that two Indian vessels were forced to turn back from the Strait of Hormuz. The two Indian ships involved were Jag Arnav and Sanmar Herald, according to the Hindustan Times.

Jag Arnav was reportedly fired upon by the Iranian Navy while Sanmar Herald, which was in the vicinity, was not harmed.

The Indian government on Saturday lodged a protest against the firing with the Iranian Ambassador to India Mohammad Fathali, ANI reported.

During the meeting with the Iranian ambassador, Foreign Secretary Vikram Misri “conveyed India’s deep concern at the shooting incident”, the Ministry of External Affairs said.

“He [Misri] 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,” the ministry stated.

The foreign secretary urged Iran to “resume at the earliest the process of facilitating India-bound ships across the Strait”, the government said.

Earlier in the day, Iran had said it was reimposing strict military controls on the Strait of Hormuz, alleging “repeated breaches of trust” by the United States.

On Friday, Tehran had fully reopened the Strait of Hormuz to commercial vessels after a 10-day ceasefire between Israel and Iran-backed militant group Hezbollah in Lebanon.

Since the conflict in West Asia broke out on February 28, Iran has effectively blocked the Strait of Hormuz, the narrow waterbody connecting the Gulf to the Arabian Sea, for most international commercial vessels, triggering a global energy crisis. About 20% of global petroleum supply passes through the maritime chokepoint.

Washington and Tehran had on April 8 agreed to a two-week ceasefire to allow further negotiations to end the conflict. While Israel, which was not involved in the talks, has not struck Iran since the ceasefire took effect, it had continued to attack Lebanon until Friday’s deal.

Peace talks between Iran and the US that were held in Islamabad collapsed on April 12. A fresh round of negotiations is reportedly expected to take place in the Pakistani capital on April 20.
