Israel escalated its military campaign against the Palestinian militant group Hamas on Tuesday. It struck symbols of the group’s control in Gaza — including the house of a prominent Palestinian leader — and fired tank shells that Palestinian officials said shut down the strip’s only power plant.

At least 100 Palestinians were killed Tuesday, including 36 who died in airstrikes and tank shelling of five homes, according to Palestinian officials. Israel has reported 53 soldiers and three civilians killed.

Israeli strike knocks out Gaza power plant, straining hospital treatment

Israel knocked out Gaza's only power plant in an air strike, possibly threatening the lives of hundreds of hospital patients.

Translated interview:

(00:25-00:45) Deputy Head of Emergency Unit at Health Ministry, Doctor Yousef Abu El Rish
Power is expected to go out completely because the quantities we have will not suffice for a few days, which threatens various hospital departments, especially intensive care units, dialysis, pediatrics, and surgery departments are threatened with collapse.

(01:22-01:29) Dialysis Patient Adnan Dweik:
My life would be threatened. Not just me, all patients suffering from renal failure. Also, transportation will become difficult. I am for example confined to a wheelchair, the ambulance comes to pick me up and brings me back. If the ambulance does not come, how will I come? If there’s no fuel, there’s no transportation.

(01:40-01:57) Dialysis Patient Mohammad Saad:
“If there’s no electricity and I cannot get treatment, I will become short of breath and cannot move. If the electricity goes out, what can we do? We belong to God and to him we shall return.”

In one strike Tuesday afternoon, 10 members of one Palestinian family were killed in tank shelling in the northern Gaza town of Jebaliya. That pushed the overall death toll since the conflict began on July 8 to at least 1,156 Palestinians and 53 Israelis, according to Gaza Health Ministry spokesman Ashraf al-Kidra and the Associated Press.

The Gaza power plant shutdown has led to serious disruptions of the flow of electricity and water to the 1.7 million people packed into the narrow territory.

As international efforts for a sustainable truce continue, the fighting entered its fourth week.
