Israel's military has bolstered its troops and rocket-defense systems in anticipation of heavy fighting with the Islamic militant group. Public bomb shelters opened and sports events and transportation were canceled in southern Israel. The Israeli army said at least 30 rockets were fired into Israel, nearly all of them either intercepted or landed in open areas.
Late Monday, Hamas announced a cease-fire had been brokered by Egyptian mediators, but new rocket fire in Gaza and air-raid sirens in Israel were heard shortly after. The Israeli military said it had retaliated with 15 airstrikes, hitting military sites for Hamas and the smaller Islamic Jihad group.
Gaza's health ministry said seven Palestinians were injured in the fresh bombings.

Haniyeh had gone into hiding earlier Monday, fearing retaliation after a rocket fired from Gaza struck an Israeli home and wounded seven people in central Israel.

Dujarric said the U.N. is continuing to work with Egypt and other concerned parties to try to de-escalate the situation. He says "further escalation is likely to make an already bad situation worse, in particular for civilians in and close to Gaza."
Dujarric noted that U.N. Mideast envoy Nikolay Mladenov will meet Guterres and brief the U.N. Security Council Tuesday, as previously scheduled.
An Israeli airstrike has destroyed a multi-story building in Gaza City that housed a Hamas-affiliated insurance company.
The Israeli military issued a statement Monday saying the building was "a secret headquarters of the Hamas terror organization" that was used by the Islamic militant group's intelligence agencies.
The powerful explosion scattered debris over a large area of the city. Prior to the main airstrike, aircraft dropped two smaller missiles on the roof of the building as a warning.
Israeli Prime Minister Benjamin Netanyahu says his country is responding "forcefully" after a rocket fired from Gaza struck a home in central Israel early Monday, wounding seven people.

The World Health Organization has delivered medical supplies to the Gaza Strip to address the blockaded territory's growing trauma and emergency care needs.
The organization said on Monday that the aid shipment, donated by the European Union, would cover the needs of up to 120,000 patients injured during demonstrations and protests.
It cited shortages of medical supplies in Gaza's stressed health care system, exacerbated by recent hostilities. Close to 190 Palestinians have been killed by Israeli fire during Hamas-orchestrated weekly rallies along the Israel-Gaza border fence.
WHO says it's scaling up its trauma care resources and appealing for funding ahead of a potential escalation and the one year anniversary of the protest movement at the end of the month.
12: 50 p.m.
A Palestinian journalist who exposed Gaza's government corruption has been acquitted by a Hamas-run court in the coastal territory.
The 34-year-old Hajar Harb had appealed a six-month prison term and fine on charges of libel and slander over her reporting. Rights groups had criticized the case as a violation of free speech in the enclave.
Harb's 2016 report highlighted misconduct at the Hamas-run health ministry, where healthy people purportedly paid doctors to help them circumvent Gaza's Israeli-Egyptian blockade by issuing referrals to hospitals abroad. The ministry denied Harb's claims and urged doctors to file lawsuits against her.
Harb celebrated her acquittal Monday, calling it "the most beautiful thing."
Rights groups charge that fair litigation is not guaranteed in Hamas' judiciary system. Hamas seized control of Gaza from the Palestinian Authority in 2007.
