Mohammed Dahlan, a longtime rival of Palestinian Authority leader Mahmoud Abbas, sent 1 million doses of coronavirus vaccine to the Gaza Strip from the United Arab Emirates.
According to a report by AFP, the vaccines arrived on Wednesday.
Gaza Health Ministry spokesman Mahmoud Hammad said the Russian-made Sputnik V COVID-19 doses were the largest shipment yet of vaccines to Gaza. They passed through the Rafah border crossing with Egypt.
Dahlan is based in the UAE; in the past, he served as security chief under Abbas.
He has organized similar aid shipments to Gaza as he seeks to promote his image among Palestinian citizenry.
