The Gaza health ministry reported on Tuesday that Nofel was injured on Friday during a protest east of Al-Bureij in central Gaza.
Two Palestinian teenagers were killed and 17 others wounded by Israeli gunfire that day during protests and clashes along the heavily fortified frontier, France24 reported.
Palestinians in Gaza have for nearly a year gathered at least weekly along the border to call on Israel to end its decade-long blockade of the enclave.
At least 250 Palestinians have been killed and more than 19,000 have also been wounded by Israeli fire during the Great March of Return clashes since then, demanding the right for Palestinians to return to their families' pre-1948 homes.
