Several loud explosions have been heard in Iran’s capital Tehran and Israel has confirmed it has launched strikes on military targets.
The Israeli military said it is conducting “precise strikes” on military targets in Iran in response to what it called “the continuous attacks from the regime in Iran against Israel”.
An Israeli Defence Forces (IDF) statement added: “Like every other sovereign country in the world, the State of Israel has the right and the duty to respond.”
Reports in the US said the White House was warned shortly before the strikes began.
Israel has been planning a response to a ballistic-missile barrage carried out by Iran on 1 October – Tehran’s second direct attack on Israel in six months.
Iranian authorities have warned Israel against launching an attack, saying any strike on Iran would be met with a stronger retaliation.
Syrian state TV has also said explosions have been heard in the Damascus countryside and central region.
It added that the country’s air defences had “confronted hostile targets” over the capital.
The strikes happened just as US Secretary of State Antony Blinken arrived home after a tour of the Middle East.
During the visit, he and other US officials had warned any Israeli response should not further escalate the conflict in the region.
