Israeli troops pushed deep into Gaza City on Sunday, ahead of a meeting between US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu focused on ending the war in the Palestinian territory.

In the Gaza Strip, Israeli troops opened fire, killing 17 Palestinians and wounding 33 others while they were attempting to access humanitarian aid in central Gaza, according to nearby Al-Awda Hospital, where the casualties were taken. Israeli strikes in central and southern Gaza killed 14 others, according to local hospitals.

In recent days, the IDF has expanded the scope of strikes across Gaza City, targeting more than 140 sites each night. As more than 800,000 of one million residents of the city have evacuated, the IDF has gained operational control of more than half of Gaza City as of Saturday,

Over the past week, Israeli strikes destroyed at least two clinics at opposite ends of Gaza City and forced two others to shut down, including a children's hospital and a specialized eye center, according to the U.N. The Jordanian government said a field hospital it had run was evacuated as Israeli troops closed in.

Explosions shake the walls of the dim basement in Gaza City where Noor Abu Hassira and her three daughters are sheltering. Abu Hassira is staying behind despite Israeli warnings to evacuate. While most Palestinians in Gaza City have fled south at some point in the 23-month long war,

The city had been spared from widespread demolitions during previous military operations there. This time is different.

The Israeli military repeated warnings Wednesday morning for residents to evacuate the devastated, famine-stricken area and said it had opened up a new route south.

Hamas issued its strongest messaging about the Israeli hostages in Gaza Thursday night, saying that Israeli Prime Minister Benjamin Netanyahu’s Gaza City ground incursion means that Israel has lost any chance of getting its hostages out of the territory – dead or alive.

Doctors Without Borders pulled its staff from Gaza City as the medical system buckled. The U.N. has warned that more hospitals may have to close.

There are also reports that a few hundred Palestinian civilians have been killed. Although the IDF has disputed these reports, it has not provided counter-numbers so far.
