Fighting in Israel and Gaza, in Photos

Israel and Gaza were on a war footing on Saturday after Palestinian militants launched one of the biggest attacks in years from the Gaza Strip, sending thousands of rockets into central and southern parts of the country as heavily armed gunmen crossed border fences into Israeli communities.

Within hours, Israeli fighter jets began airstrikes on targets inside Gaza, as Prime Minister Benjamin Netanyahu of Israel said on television: “We are at war.” Muhammad Deif, the head of the military wing of Hamas, the Islamic militant organization that controls Gaza, said earlier that the group had decided to launch an “operation” so that “the enemy will understand that the time of their rampaging without accountability has ended.”

Here are images from the confrontation.
