The United States and Israel launched a wave of strikes against targets in Iranian cities on Saturday (Feb 28), triggering explosions and columns of smoke in the capital Tehran.

Iran responded by launching retaliatory missile attacks, according to the Israeli military, as US diplomats in the Gulf and Israeli civilians were ordered to seek shelter.

The attacks came after US President Donald Trump expressed frustration at Iran's stance in negotiations over its nuclear and missile programmes.

Announcing the start of "massive" combat operations, Trump said Washington's goal was "eliminating imminent threats" from Iran.
