Air raid sirens went off in Tel Aviv for a third day running on Saturday, sending people scuttling for cover as TV images showed the Iron Dome anti-missile system firing on an incoming rocket.

AFP correspondents at the scene said people could be seen running to find shelter as the sirens wailed, a day after a rocket crashed into the sea off central Tel Aviv.

"First interception for the fifth Iron Dome battery located in the greater Tel Aviv area" said Avital Leibovich the spoksperson of the Israel Army on her twitter.
