Iran's missile and drone attack on Israel raises the risk of an escalation in the region, the BBC's Middle East correspondent says.

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

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

With Iran and Israel in direct confrontation, BBC security correspondent Frank Gardner considers what comes next.

IDF spokesperson Daniel Hagari says the drones could take several hours to arrive.

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

This is uncharted territory fraught with risk, writes our chief international correspondent.

President Joe Biden met promptly with US national security officials after Iran launched its attack.
