Israel has "resumed full-force fighting" against Hamas in the Gaza Strip, Israeli Prime Minister Benjamin Netanyahu said on Tuesday.
In a press conference, the head of the Israeli government declared that this was just the beginning and that Israel will achieve all its objectives in Gaza.
His comments came after Israeli jets launched massive airstrikes against what the military said were Hamas targets in Gaza.
More than 400 people have been killed in the attacks and hundreds more have been injured.
The fragile ceasefire had held until now, but this new wave of attacks suggests that plans for a permanent end to the war may be off the table.
Airstrikes that hit Beit Lahia, Rafah, Nuseirat and Al-Mawasi on Tuesday shattered the relative peace that Gazans had experienced since January, and hospitals have once again been overwhelmed with casualties.
Key Hamas figures were killed in the airstrikes, including Major General Mahmoud Abu Watfa, deputy interior minister in Gaza and Hamas's top security official. (A2 Televizion)
