Indian Foreign Minister S Jaishankar has said he is hopeful that talks with Iran are beginning to ease shipping disruptions for the country's vessels in the Strait of Hormuz.

"I am at the moment engaged in talking to them and my talking has yielded some results," he told the Financial Times.

He added, however, that there was no "blanket arrangement" for all Indian ships to pass through the narrow waterway, a vital oil shipping channel.

Two Indian-flagged gas tankers passed through the strait on Saturday after discussions progressed between Delhi and Tehran. Twenty-two Indian-flagged vessels are still waiting for clearance to pass through the channel.

The war in the Middle East - which began after US and Israel launched wide-ranging strikes on Iran on 28 February - has led to Iran almost completely blocking ship movements through the channel. Iran has also launched attacks on Israel and US-allied states in the Gulf, which have extended to non-military targets.
