Israeli warplanes struck dozens of targets in Gaza early on Friday after rockets were fired at Tel Aviv for the first time since the 2014 war between Israel and Hamas.

In the hours after the Israeli strikes, another nine rockets were fired from Gaza towards southern Israel, according to the Israeli military.

No fatalities were reported on either side but the escalation comes after weeks of tension on the Gaza border and at a politically sensitive moment in the middle of Israel’s election.

The incident began at around 9pm on Thursday when two rockets were fired from Gaza towards Tel Aviv, Israel’s second largest city.

Sirens wailed and municipal bomb shelters were opened for the first time since the 2014 war.
