Israel announced that it has identified the body of a fourth hostage this week. Ron Benjamin, 53, was killed during the Oct. 7 Hamas attack and taken into Gaza, according to the Israel Defense Forces.

The bodies of three other hostages were also recovered in a tunnel in the same operation, according to the IDF.

Benjamin was a family man who loved cycling, the Hostages Families Forum said in a statement.

"He used to go out for a ride every Saturday, just as he did on that fateful Saturday when he was taken hostage from the Kibbutz Be’eri area while on a cycling trip," the statement said.

More than 630,000 people have fled Rafah since May 6 amid widening operations by Israel’s military, with many seeking refuge in Al-Mawasi and Deir al-Balah -- areas overcrowded with "dire conditions" -- according to the United Nations.

Humanitarian assistance shipments delivered to Gaza through the U.S.’ maritime corridor should not replace aid coming into the enclave through land crossings where "barely 100 trucks of aid a day" entered over the last two weeks -- about a sixth of the level needed to stave off famine -- USAID Administrator Samantha Power said in a statement Friday.

"Every moment that a crossing is not open, that trucks are not moving, or where aid cannot safely be distributed, increases the terrible human costs of this conflict," Power said.

Supplies coming into Gaza through the temporary pier Friday include contributions from the U.S., United Arab Emirates and the United Kingdom.

But, the statement doesn’t say how much aid is now being moved through the corridor at this point or how much of it is sitting in Cyprus waiting to be shipped -- so it’s still unclear if and when these deliveries might have a substantial impact.

Almost 1,400 buildings have likely been damaged or destroyed in Rafah, Gaza, since May 4, according to an analysis of satellite imagery by two university researchers.

Data from the radar-enabled Copernicus Sentinel-1 satellite operated by the European Space Agency was used to analyze the effects of fighting on the terrain and buildings of Gaza, according to Corey Scher, of the CUNY Graduate Center, and Jamon Van Den Hoek, of Oregon State University.

Between May 4 and May 8, the researchers found evidence that 895 buildings were likely damaged or destroyed in Rafah. From May 8 to May 16 they counted 487.

Since Oct. 5, the researchers have found evidence of likely damage or destruction to 18,176 of the 48,678 buildings in Rafah.
