Doctors Without Borders, known by its French acronym MSF, has issued a statement saying it is mourning its 10th staff member killed since Israel’s military campaign started in Gaza, Al Jazeera reports.

“MSF is shocked and saddened by the killing of our colleague Alaa Abd-Elsalam Ali Okal by an Israeli air strike on his apartment building in Deir el-Balah, central Gaza,” it said.

“Along with hundreds of others across the Gaza Strip, Alaa Abd-Elsalam Ali Okal was killed in the early morning of 18 March following the resumption of Israeli attacks.”

The 29-year-old was a laundry worker with the organisation and “played an important role in supporting people in need of medical care at MSF’s field hospital in Deir el-Balah”.

“We condemn the killing of our colleague and call yet again for the respect and protection of civilians.”
