Ramallah: After Dr. Mohammed Al-Osaibi was killed by Israeli police on Saturday at the entrance to Al-Aqsa Mosque, Palestinian towns throughout Israel observed a general strike and day of mourning on Sunday. Employees from the Arab public education system, Arab local government shops, and other institutions participated in the strike. Protests were concentrated in the Galilee, the Triangle, and the Negev. Al-Osaibi, a Bedouin from the southern Israeli village of Hura, was shot dead early on Saturday morning in front of the Al-Aqsa Mosque in occupied East Jerusalem.

Suhail Diab, the mayor of Tamra in the Galilee, said the attack was meant to convey that the killing was "a criminal operation against a doctor who was killed in cold blood by Israeli police bullets under false pretences." According to Diab, Israeli police claims that Al-Osaibi attempted to take a police officer's gun and that the area where the incident occurred had no operational security cameras, as well as their assertions that police body cameras had malfunctioned, were untrue.
