It follows daytime attacks from both sides, with Israeli strikes in Tehran continuing and Iran firing more missiles towards Israel.

Israel has launched hundreds of air strikes since the early hours of June 13th. Iran has responded with salvoes of ballistic missiles and drones, although only a handful have penetrated Israel’s defence systems.

The operation by the Israeli spy agency used stealth to target Iranian air defenses and missiles.

Many of those confirmed dead were women and children, according to the authorities, although they have yet to publicly name all of the victims.

Israel and Iran have opened a new chapter in their long history of conflict when Israel launched a major attack with strikes early Friday on Tehran.

An exchange of strikes on refineries and gas facilities was limited but raised the risks to an industry with broad economic impacts.

It is the first time that Britain has advised against travel to any part of Israel since 2013, when the FCDO set up its dedicated travel advice pages. Starmer has not ruled out offering air support to defend Israel from Iranian attacks, as additional RAF fighter jets and other military aircraft were deployed to the Middle East.

Israel’s El Al Airlines announced on Sunday that it has suspended all flights until at least June 19, with additional cancellations to many European cities extending to June 23, due to the ongoing conflict between Israel and Iran.
