The deal, brokered by Egyptian and United Nations officials, was designed to restore calm and end the Israeli onslaught on Hamas positions and other violence that resulted in the deaths of four Palestinians and one Israeli soldier on Friday.
Hamas spokesman Fawzi Barhoum announced the deal early on Saturday morning, saying that it had been active from midnight local time on Friday.
“We reached [an agreement] to return to the previous state of calm between the [Israeli] occupation and the Palestinian factions,” Barhoum said.
Israel confirmed the agreement later on Saturday, with the army saying in a separate statement that communities near Gaza could return to normal activity, according to the Israeli daily Haaretz.
“At the end of an assessment by the southern command this morning it was decided to maintain a full civilian routine in the communities close to the Gaza Strip,” Haaretz quoted the statement as saying.
The deal came after Israeli forces killed four Palestinians in the Gaza strip on Friday.
Israeli soldiers fired live bullets and tear gas canisters towards Palestinian protesters gathered along the fence with Israel, killing 27-year-old Mohammad Sharif Badwan and wounding 120 others, according to health officials in Gaza.
Hamas also said three of its members were killed earlier in the day after Israel launched large-scale attacks in the southern part of the enclave. Sixty Hamas targets were hit by Israeli forces on Friday night.
Israeli forces said the attacks came after one of its soldiers, Staff Sergeant Aviv Levy, 20, was hit by Palestinian gunmen. They later announced the soldier had succumbed to his wounds, marking the first Israeli military fatality in the area since the 2014 Gaza war.
More than two million Palestinians are packed into the Gaza Strip, a territory the size of the US city of Detroit – about 360sq km – which has been described as “the world’s largest open-air prison”.
Israel withdrew its troops and settlers from Gaza in 2005 but, citing security concerns, maintains tight control of its land and sea borders, which has reduced its economy to a state of collapse. Egypt also restricts movement in and out of Gaza on its border.
While it appeared that relative calm had returned to the area on Saturday, Phyllis Bennis, a programme director at the US-based Institute for Policy Studies, said it was unlikely that any ceasefire agreement would hold.
“It is important that they use the word calm [in the announcement] and not the word peace,” Bennis told Al Jazeera.
“There has been no calm in Gaza for many, many decades,” she said. “If there is a ceasefire that holds briefly it will not hold for very long I’m afraid.”
Her view was echoed by Usama Antar, a political analyst in Gaza City.
“I don’t think this ceasefire will last for a long time. It’s very fragile,” he told Al Jazeera.
“Unfortunately we will have a couple of days of calm, and after that, we will have the same situation because the many problems of the people in the Gaza Strip are still not solved.”
Al Jazeera’s Stefanie Dekker, reporting from Gaza City, called the deal to restore calm a temporary solution that is unlikely to resolve long-standing issues in the region.
“The pattern of escalation-ceasefire, escalation-ceasefire between Israel and Hamas will continue to go on unless there is a long-term solution to alleviate the situation for the people here,” she said.
“Two million people are living under this blockade and everyone says the same thing – how impossible life has become here”.
Despite the deal, Israeli forces targeted a Hamas position on Saturday morning after individuals crossed from Gaza into Israel, according to Haaretz.
Also on Saturday, a flaming balloon sent from Gaza started a fire at an Israeli farm near the fence.
Friday’s violence comes after nearly four months of protests by Palestinians along the fence with Israel.
Palestinians have been protesting every Friday since March 30, demanding their right to return to the homes and land their families were expelled from 70 years ago.
Since the protests began, Israeli forces have killed more than 140 Palestinians in the coastal enclave and wounded over 16,000 people, according to health officials in Gaza.
