The fighting in the Gaza strip intensified Sunday

An Israeli hospital says it’s been hit by shrapnel after an rocket fired from the Gaza Strip was intercepted by Israel’s Iron Dome defense system.

Dr. Hezi Levy, director of the Barzilai University Medical Center in the city of Ashkelon, says there were no injuries Sunday, but the hospital’s oncology unit suffered damage. He says the interception sent a large amount of metal fragments falling onto the hospital.

The medical center released a video of water pouring through the ceiling into a hallway after pipes were damaged by the strike.

The Israeli military says it’s struck a series of new targets in the Gaza Strip, including sites it says were hidden in the homes of Hamas militants or concealed in civilian areas.

In an announcement Sunday, the military said jets and attack helicopters have struck tunnels, military compounds, a weapons-manufacturing facility and several rocket-launching sites.

The army says it’s struck some 260 targets since fighting erupted a day earlier. Gaza militants have fired hundreds of rockets during that time, and air raid sirens continue to sound throughout southern Israel.

Six Palestinians, including a pregnant woman and her 14-month-old niece, as well as one Israeli man have been killed in the fighting.

Israel’s main rescue service says a rocket from Gaza has wounded three Israelis, including two seriously.

The Magen David Adom service says the two men, ages 40 and 22, suffered “multisystem trauma” after being hit with shrapnel Sunday in the coastal city of Ashkelon. The third man, 50, was moderately wounded.

Earlier in the day, an Israeli man was killed in Ashkelon, the first Israeli to die from rocket fire since the 2014 war with Hamas militants.

Gaza militants have fired more than 400 rockets at Israel, with several direct hits on residential buildings. A midday burst struck a home in the city of Beersheba.

Gaza’s Heath Ministry says six Palestinians have been killed by retaliatory Israeli airstrikes, including a pregnant woman and her 14-month-old niece. The Israeli military says it was not involved in the incident.
