A Palestinian was killed by Israeli fire during clashes and protests along the Gaza border on Saturday marking a year since demonstrations erupted there, the enclave's health ministry said.

Adham Amara, 17, was hit in the face east of Gaza City, ministry spokesman Ashraf al-Qudra said. Tens of thousands of Palestinians were gathered along the Gaza-Israel border and dozens were wounded.

Earlier Saturday, another Palestinian was killed by Israeli fire in an overnight demonstration ahead of the main protest, the ministry said.
