President Donald Trump has suggested that he would turn to an unspecified project for Cuba, the Caribbean island already facing a US energy blockade, after the war against Iran.

"We want to fix, finish this one first -- but that will be just a question of time before you and a lot of unbelievable people are going to be going back to Cuba," Trump said at a White House reception.

India's access to crucial energy supplies received a temporary boost on Friday after US Treasury Secretary Scott Bessent announced a 30-day waiver allowing Indian refiners to purchase Russian oil. 

The move comes as the administration seeks to stabilise global energy markets amid rising tensions in the Middle East.

Prime Minister Anthony Albanese has said that three Australian defence personnel were on board a United States submarine that sank an Iranian warship, IRIS Dena, with a torpedo in the Indian Ocean. He stressed they did not take part in the attack.

The strike, which occurred off the southern coast of Sri Lanka this week, marked the first time since World War Two that the US has sunk an enemy vessel with a torpedo. Sri Lankan authorities recovered the bodies of 87 sailors.

The IRIS Dena was returning home after visiting India for naval exercises.

Bahrain has said that Iran had struck a hotel and two residential buildings in the capital Manama.

The attack came a day after an Iranian missile strike sparked a fire at Bahrain's main state-owned oil refinery as Tehran pressed attacks across the Gulf countries.

"Iranian aggression targeted a hotel & 2 residential buildings in Manama," Bahrain's interior ministry posted on X while correcting a previous announcement that two hotels and one residential building had been hit.

It reported "no loss of life".

It said the attack sparked a fire in one of the residential buildings, which had been extinguished.

The Israeli military announced a "next phase" in the war and bombed Lebanon's Beirut.

It said it killed Hezbollah's commander Zaid Ali Jumaa in Beirut.

"Jumaa served as Hezbollah’s head of artillery in southern Lebanon and was responsible for launching thousands of rockets, missiles and UAVs from Lebanon toward Israel. He also led the 2015 anti-tank missile attack in Mount Dov that killed an IDF officer and soldier," the Israel Defense Forces posted on X.

Lebanon was dragged into the widening conflict on Monday, when Iran-backed Hezbollah attacked Israel to avenge the killing of Supreme Leader Ali Khamenei.

The raging war in the Middle East entered its seventh day on Friday. The war broke out when Israel and the US attacked Iran last Saturday, killing 86-year-old Supreme Leader Ali Khamenei. 

Iran then fired a missile barrage at Israel and at multiple American military bases in Gulf countries. The war spread to Asia as the US sank an Iranian warship off the coast of Sri Lanka on Wednesday, killing about 80 people.
