Live blog: Gaza under attack
Israel's Channel 2 reports that 50 percent of Israeli cabinet ministers were opposed to the ceasefire agreement that came into place just over an hour ago.
At least three senior politicians, Interior, Economy and Internal Security Ministers, are known to have voiced their opposition to the deal.
The head of Eshkol Regional Council in southern Israel has said he will not instruct residents to return to their homes for the time being.
Earlier, Hamas spokesperson Sami Abu Zuhri said that residents of border communities would not be able to return home until after a decision from Hamas.
Gaza's Health Ministry has announced that two young brothers were killed when the car they were travelling in was struck in Khan Younis moments before the ceasefire came into effect.
Palestine's Interior Ministry has warned people not to shoot in the air in celebration, after reports of injuries.
"The Interior Ministry demands that citizens immediately stop shooting in the air, and find other methods of celebrating out of concern for their lives."
There are currently huge rallies in cities throughout the Gaza Strip.
Thousands of people have taken to the streets of the Gaza Strip to celebrate the start of the ceasefire and what many are calling a victory for the resistance.
Rocket sirens have been sounding in Israel but there have been no reports of rockets falling or being intercepted by the Iron Dome system.
