The closure of the Rafah crossing between Egypt and Gaza has prevented the medical evacuations of at least 2,000 patients, a World Health Organization official said, calling for Rafah and other routes to be reopened, Reuters reports.

Before the closure, “approximately 50 critical patients a day left Gaza … It means that since the 7th of May at least 2,000 people have been unable to leave Gaza to receive medical care,” said Rik Peeperkorn, WHO representative in the West Bank and Gaza.

Movement through the nearby Israeli-controlled Kerem Shalom crossing, which Peeperkorn described as unsafe, has been impeded by insecurity and logistical challenges.

At least 10,000 people are in need of evacuation from Gaza, Peeperkorn said, adding that this was an underestimate of the number needing critical care for both war traumas and chronic diseases.

“We need more routes for medical emergency evacuation (medevac), we would like to see Kerem Shalom and other routes also opened for medevac where patients can then be referred to the referral hospitals in East Jerusalem and the West Bank,” Peeperkorn said.

A group of five children who had been evacuated from northern Gaza to Nasser Hospital in Khan Younis and were reportedly poised to leave the strip were still awaiting evacuation, Peeperkorn said.
