Hamas police officers guard a truck containing a shipment of Russian Sputnik V coronavirus vaccines at the Kerem Shalom border crossing, in Rafah, Gaza Strip, Wednesday, Feb. 17, 2021. The announcement by Mohammed Dahlan came a day after Abbas' government managed to deliver 2,000 vaccines to Gaza and appeared to be aimed in part at embarrassing the Palestinian president. Dahlan was once a bitter foe of Hamas when he served as the Palestinian security chief in Gaza. The expected delivery of vaccines could further boost Dahlan's standing in the territory as Abbas continues to struggle to procure vaccines for his people. With Emirati money, Dahlan’s group has delivered tons of medical aid, including an oxygen generator, to support Gaza’s weak health care system dealing with COVID-19 patients.
