Israel's defence minister warns that "Tehran will burn" if Iran keeps firing missiles, after both sides exchanged strikes overnight.
Explosions were heard in Tel Aviv, Jerusalem and Tehran after Iran launched waves of missiles in retaliation for Israeli strikes which targeted Iran's nuclear programme on Friday.
Iran warns the UK, US and France it will target their bases and ships in the region if they help stop the strikes on Israel, according to state media reports.
Downing Street hasn't responded yet, but our political correspondent understands the UK has not taken part in any military action, including efforts to defend Israel against strikes.
In Israel, officials say three people have been killed and dozens injured, while Iranian state TV reports 60 people have been killed in a strike in Tehran.
Israeli PM Netanyahu has opened another open-front war, and the Iranian regime is going to see this as a battle for survival.
