Mourners laid Palestinian medic Abdullah al-Qutati, 22, to rest in the southern city of Rafah, according to Palestinian Media.
Ali al-Aloul, 55, and Ahmed Abu Louli, 40, were also buried in Rafah, amid angry chants against Israel by mourners.
Since March, more than 160 people have been martyred and thousands more injured by Israeli occupation forces fire during protests against the decades-long Israeli occupation and 11-year blockade on the Gaza Strip, which has gutted the coastal enclave’s economy and deprived its roughly 2 million inhabitants of basic commodities.
