THERE has been a night of intense fighting between Israel and Iran, with the two sides trading fire and explosions heard in Tel Aviv, Jerusalem and Tehran.

Iran launched waves of missiles in retaliation for Israeli strikes that targeted Iran's nuclear facilities and military bases on Friday, killing senior commanders and six scientists.

Ballistic missiles hit parts of Israel overnight, with several alerts issued for the public to take shelter - the BBC's Ione Wells reported hearing an explosion in Jerusalem.

At least two people have been killed and dozens injured, according to Israeli emergency services.

Iran's representative to the UN says 78 people were killed in Friday's Israeli strikes and at least 320 injured, the "overwhelming majority" of whom are civilians.
