GAZA, Aug. 5 (Xinhua) -- At least four Palestinians were wounded on Sunday by Israeli air raids on the Gaza Strip, official security sources said.
"An Israeli scouting warplane fired two missiles on gatherings of two groups of young men who were attempting to fly kites and helium balloons, laden with incendiary material to the Israeli side," the sources told Xinhua.
The wounded have been transferred to the Indonesian Hospital north of besieged enclave, he added.
Some 157 Palestinians were killed and more than 17,000 were injured by Israeli forces as they took part in the "Great March of Return" protests in the besieged Gaza Strip.
The protests demand the return of Palestinians refugees, who were forced to leave their cities during the Arab-Israeli war in 1948, as well as lifting the blockade Israel has been imposing on Gaza since 2007.
