Nayef Rajoub, a senior member of the Hamas terrorist group, recuperated in a private hospital in Tel Aviv after undergoing spine surgery.

Rajoub apparently stayed in the Assuta Medical Center’s Ramat Hahayal hospital for a few days, but the hospital said it could not confirm or deny his hospitalization, citing privacy concerns, Israel Hayom reported.

In 2006, Rajoub was elected to the Palestinian parliament as a Hamas candidate and then tapped to serve as religious affairs minister. Several months later, after Hamas captured Israeli soldier Gilad Shalit, Israel put Rajoub in administrative detention along with other senior Hamas officials. He was released four years later, several months before the Shalit prisoner swap.

This is not the first time Israeli hospitals have treated a notable Palestinian figure. In 2013, Hamas leader Ismail Haniyeh’s granddaughter was treated for a rare disease at the Schneider Children’s Medical Center. Palestinian Authority President Mahmoud Abbas’s wife, Amina, underwent an operation at Assuta Medical Center in June 2014.
