Israeli military aircraft bombed Hamas targets in the Gaza Strip early on Friday, hours after two rockets were launched at Tel Aviv in the first such attack since a 2014 war.
The Israeli military said its Iron Dome defense system intercepted all but one of six more missiles that were fired at Israel.
In a statement, the Israeli military said it had struck “approximately 100 military targets” belonging to Hamas, the Islamist militant group which controls Gaza.
Reuters was unable to immediately verify the claims.
Palestinian news media reported strikes throughout Gaza, from Rafah in the south to the north of the densely populated coastal strip that is home to two million Palestinians.
Some of the buildings targeted had been evacuated as a precaution, as Hamas had expected an Israeli response.
Health ministry officials in Gaza said two people, a man and a woman, were wounded when their house was damaged in Rafah in the early morning.
Witnesses said powerful explosions from the air strikes rocked buildings in Gaza and lit the skies over targeted sites.
