An explosion was heard in Jerusalem on Saturday after air raid sirens warned of an incoming Iranian missile attack, AFP is reporting.

The Israeli military said earlier that air defences were “operating to intercept the threat”, before giving the all-clear.

The US state department has approved the sale of $151.8m worth of munitions to Israel on Friday amid the escalating Middle East war.

The sale of 12,000 requested 1,000-pound (470km) bomb bodies was approved by the state department’s bureau of political-military affairs, according to a press release on Friday.

“The proposed sale will improve Israel’s capability to meet current and future threats, strengthen its homeland defense, and serve as a deterrent to regional threats,” the bureau said in a statement cited by the AFP news agency.

Hello and welcome to our live coverage of the US-Israel war on Iran as the conflict continues to expand as it enters its second week.

Donald Trump has declared that he would only accept Tehran’s “unconditional surrender” and Israel has traded fresh attacks with Iran and Lebanon.

The US president’s comments on social media on Friday came hours after Iran’s president announced that unnamed countries had begun mediation efforts, briefly raising the possibility, however faint, of a diplomatic resolution.

If you are just catching up on the latest, here is a quick summary of what you need to know.

• The United Arab Emirates, Kuwait, Qatar, Bahrain and Saudi Arabia all reported fresh drone and missile attacks.

• Israel also launched a new wave of attacks on Iran, saying 50 of its warplanes had hit a bunker still being used by Iran’s leadership beneath slain supreme leader Ayatollah Ali Khamenei’s destroyed Tehran compound.

• Russia has been sharing intelligence with Iran about US targets in the region, according to news reports. In response US defence secretary Pete Hegseth said the US was “not concerned” and was “tracking everything” and factoring it into battle plans.

• At least 1,332 people have been killed in Iran since the US-Israel first launched strikes on 28 February, Iravani said, citing the Iranian Red Crescent Society.

• The Lebanese health ministry has reported 123 people killed and 683 wounded as a result of Israeli attacks. About 300,000 people have been displaced in Lebanon in the past four days, according to the Norwegian Refugee Council.
