Georgios Petropoulos, who heads OCHA in Gaza, has described witnessing the aftermath of an Israeli attack that “vaporised” the bodies of victims, Al Jazeera reports.

In remarks reported by Israel’s Haaretz newspaper, Petropoulos said the site of the attack in al-Mawasi looked like Nagasaki, the Japanese city where US forces dropped an atomic bomb in 1945.

“They counted the bodies, but there are people who simply vaporised,” Petropoulos said. “Ten or twenty people who were known to be in the tents have simply vanished. “I was at the hospital after the bombing, it looked like a slaughterhouse, blood everywhere.”

Haaretz did not specify the exact attack that Petropoulos was referring to. But the article noted there have been at least eight attacks on al-Mawasi, a sandy area that Israel has designated as a “safe zone”, that killed scores in November, and another on December 4 that destroyed 21 tents and killed at least 23 people.
