At least 15 Palestinians were killed and hundreds injured by Israeli security forces confronting one of the largest Palestinian demonstrations along the Israel-Gaza border in recent years, Gaza medical officials said.
Tens of thousands of Palestinians, pressing for a right of return for refugees to what is now Israel, gathered along the fenced 65-km (40-mile) frontier where tents were erected for a planned six-week protest, local officials said. The Israeli military estimate was 30,000.
Families brought their children to the encampments just a few hundred meters from the Israeli security barrier with the Hamas Islamist-run enclave, and football fields were marked in the sand and scout bands played.
But as the day wore on, hundreds of Palestinian youths ignored calls from the organizers and the Israeli military to stay away from the frontier, where Israeli soldiers across the border kept watch from dirt mound embankments.
