Israel said Sunday that it was resuming its ground offensive and airstrikes in the Gaza Strip early Sunday, closing a unilateral 24-hour cease-fire window after the Islamic militant group Hamas fired a salvo of rockets at southern Israel.
“Due to Hamas’ incessant rocket fire during the humanitarian window, we are renewing our aerial, naval, and ground activity in Gaza,” an Israel Defense Forces spokesman tweeted Sunday. The next tweet read, “The IDF has repeatedly urged the civilian population of Gaza not to approach combat zones.”
The Israeli military said about a dozen rockets had been fired from Gaza since midnight Sunday, without causing any reported casualties or damage. Israel’s Cabinet had decided to extend the cease-fire for 24 hours, until midnight Monday (5 p.m. Eastern Time Sunday), but warned that its military would respond to any fire from Gaza and would continue to demolish cross-border tunnels used by militants to stage attacks.
The rocket fire began late Saturday after Hamas, who have demanded the lifting of an Israeli and Egyptian blockade on the territory and the release of prisoners, refused to extend the truce.
“Once again Hamas is cynically using the people of Gaza as a human shield,” Israeli Prime Minister Benjamin Netanyahu’s office said in a statement.
Shortly thereafter, clashes erupted between Israeli troops and Gaza militants and the sounds of explosions echoed across the coastal territory. The Islamic Jihad group said one of its field commanders was killed by tank fire near the southern Gaza town of Khan Younis.
Gaza health officials claim that the 20-day offensive has killed more than 1,050 Palestinians, though it is not clear how many were civilians and how many were Hamas militants. Israel has lost 43 soldiers, while two Israeli civilians and a Thai worker were also killed by rocket and mortar attacks from Gaza.
The Hamas rejection of a further lull after fighting was halted for 12 hours Saturday complicated the efforts of U.S. Secretary of State John Kerry and European foreign ministers, who were meeting in Paris in hopes of transforming the cease-fire into a more sustainable truce.
Israel launched its military operation on July 8 and later sent ground forces into Gaza to stop relentless rocket fire and to destroy a sophisticated network of Hamas tunnels that could be used to infiltrate the country.
The military says it is doing its utmost to prevent civilian casualties, including by sending evacuation warnings to residents in targeted areas, and blames Hamas for putting civilians in harm’s way.
Hamas and other militants in Gaza have fired more than 2,400 rockets at Israel since hostilities began on July 8, many deep into the Israeli heartland and toward most of the country’s major cities. Casualties in the Israeli side have stayed relatively low thanks to Israel’s sophisticated Iron Dome missile defense system and because residents have been vigilant about seeking shelter quickly upon hearing the air raid sirens.
Hamas spokesman Sami Abu Zuhri said any truce must include a withdrawal of Israeli forces from Gaza, and that tens of thousands of displaced people must be allowed to return to their homes. Israel’s current terms are “not acceptable,” he said in a text message to journalists.
Israel’s acceptance of the cease-fire extension was premised on its soldiers remaining in Gaza to destroy the more than 30 tunnels the military says it has already found in the densely populated coastal strip. Israel says the tunnels represent a strategic threat because they allow Hamas fighters to carry out attacks on Israeli territory.
