Iran launched a new wave of attacks at Israeli and American bases on Thursday morning and threatened that the US would “bitterly regret” torpedoing an Iranian warship in the Indian Ocean.
Elsewhere, a religious leader called for “Trump’s blood”, while Israel said it had begun a “large-scale” attack on Tehran.
Israel announced multiple incoming missile attacks and air sirens sounded in Tel Aviv and Jerusalem.

Iran launched its large Khorramshahr-4 missiles in an attack on Thursday targeting Israel, the country’s paramilitary Revolutionary Guard said.
The Guard said the missiles had a one-ton warhead. The missiles can also be multiple warhead. Israel has said Iran used cluster munitions in attacks.
The Guard claimed attacks in Bahrain, Kuwait and the United Arab Emirates as well.
The Israeli military said it launched targeted attacks in Lebanon at the Iranian-backed Hezbollah militant group and a “large-scale wave of strikes against infrastructure” in Iran’s capital, without elaborating.
Explosions were heard in multiple locations in Tehran a short time later.
The US navy sank an Iranian warship on Tuesday night in the Indian Ocean, killing at least 87 Iranian sailors, which Iranian foreign minister Abbas Araghchi decried as “an atrocity at sea”.
“Frigate Dena, a guest of India’s navy carrying almost 130 sailors, was struck in international waters without warning,” he wrote on social media.
“Mark my words: The US will come to bitterly regret (the) precedent it has set.”

Officials in New Delhi said the Iranian warship had participated in naval exercises hosted by India before heading out into international waters in the Indian Ocean on its way home.
Sri Lanka’s navy said it had responded to a distress signal from the IRIS Dena, but by the time it reached the location, there was no sign of the ship, just patches of oil and sailors floating in the water. The rescued mariners were taken to a hospital in the town of Galle, on Sri Lanka’s southern coast.
India’s navy and defence ministry said the Iranian warship had participated in the International Fleet Review and the multilateral naval exercise MILAN 2026, organised by the Indian navy in the port of Visakhapatnam from February 15 to February 25. The ministry said 74 countries had joined the events.
The Iranian warship was seen sailing at sea during the exercises in a February 17 post on X by the Indian navy. Another image showed several of its crew members posing on deck with the Iranian flag in the background.
Mr Araghchi stressed that the frigate had been “a guest” of India’s navy. The Indian government has not yet publicly commented on the incident.
Sri Lanka’s media minister and government spokesman, Nalinda Jayatissa, told its parliament on Thursday that another Iranian ship had arrived in its waters. Mr Jayatissa did not provide further details about the ship or the number of people on board.
Ayatollah Abdollah Javadi Amoli, in one of the few clerical statements so far from Iran, said the country was “on the verge of a great test” and called on state television for “the shedding of Zionist blood, the shedding of Trump’s blood”.
“Fight the oppressive America, his blood is on my shoulders,” he said in a rare call for violence from an ayatollah, one of the highest ranks within the clergy of Shiite Islam.
The US and Israel launched the war on Saturday, targeting Iran’s leadership, missile arsenal and nuclear programme while suggesting that toppling the government is a goal.
But the exact aims and timelines have repeatedly shifted, signalling an open-ended conflict.
The war has killed more than 1,230 people in Iran, more than 70 in Lebanon and around a dozen in Israel, according to officials in those countries.

It has disrupted the supply of the world’s oil and gas, snarled international shipping and stranded hundreds of thousands of travellers in the Middle East.
A drone crashed on Thursday near the airport in Nakhchivan, an Azerbaijan exclave that borders the north of Iran and is separated from the rest of the country by Armenia. Another drone fell near a school and two civilians were injured, Azerbaijan’s foreign ministry said.
Iran’s general staff of the armed forces denied on Thursday that it had launched a drone toward Azerbaijan. The denial comes, however, as Iran has repeatedly denied targeting oil infrastructure and other civilian targets during the war, despite its drone and missile fire hitting those sites.
Qatar evacuated residents near the US embassy in Doha as a temporary precaution and fighter jets could be heard overhead early in the United Arab Emirates city of Dubai.
Saudi Arabia said it destroyed a drone in its province bordering Jordan, and a new attack off the coast of Kuwait appeared to expand the area where commercial shipping was in danger.

An explosion rocked the area early on Thursday, according to the United Kingdom Maritime Trade Operations Centre run by the British military. It said a tanker apparently came under attack, but the agency did not offer a cause. Iran has attacked ships by attaching limpet mines to them in the past.
Prior attacks since fighting began on Saturday have happened in the Gulf of Oman and the Strait of Hormuz, which connects it to the Persian Gulf and through which about a fifth of the world’s oil is shipped.
US stocks rebounded on Wednesday after oil prices stopped spiking and reports gave encouraging updates on the American economy.
But oil prices resumed their ascent early on Thursday and Brent crude, the international standard, was up some 15% from the start of the conflict as Iranian attacks have disrupted traffic through the strait.
