Israel says 99% percent of projectiles fired at it by Iran overnight were intercepted by it and its allies.

Loud explosions could be heard across the city as air defence systems shot down objects from the sky.

People were seen drinking in the streets of Tel Aviv despite Iran confirming a drone launch.
