Two Lebanese security officials say four people in Lebanon were killed when Israeli soldiers opened fire at protesters who approached the border with Israel. The security officials said there were injuries as well. Both spoke on condition of anonymity because they were not authorized to speak to the media. The demonstration came as a large crowd of protesters also tried to cross into the Israeli-controlled Golan Heights from neighboring Syria. The unrest came as the Palestinians marked the "nakba," or "catastrophe," the term they use to describe the uprooting they suffered at the time of Israel's founding on May 15, 1948.
