JERUSALEM - The latest on the Israeli-Palestinian conflict (all times local):

3 a.m.

The Palestinians' ambassador at the United Nations is appealing to the U.N. Security Council for immediate international protection for Palestinian civilians, especially in the Gaza Strip, where 18 Palestinians were killed by Israeli fire last week.

Ambassador Riyad Mansour claims in a letter to the council Tuesday that Israel has adopted "a shoot-to-kill policy" during what he calls peaceful protests.

Mansour strongly backs Secretary-General Antonio Guterres' call for an independent investigation of the killings. He says over 1,500 Palestinians were wounded.

Mansour accuses Israel of violating international law and "intentionally, grossly and systematically" violating its legal obligation to protect civilians.

Israel warned Tuesday that protesters near Israel's border are putting their lives at risk.

Palestinian health officials say a 25-year-old man has been killed in clashes with Israeli troops in the Gaza Strip.

The Palestinian Health Ministry said the man was shot east of Bureij, near the Israeli border in central Gaza, where he was throwing stones toward soldiers.

It was the first deadly incident since Friday, when 18 Gazans were killed during widespread protests and clashes along the Israeli border.

Large demonstrations are planned again this Friday, raising the possibility of further bloodshed.

Israel's defence minister says the military will not change its tough response to Hamas-led mass protests near Gaza's border with Israel, warning that "anyone who approaches the border is putting their life in danger."

Avigdor Lieberman spoke Tuesday near Gaza, where 18 Palestinians were killed by Israeli fire Friday, the first day of what Hamas says will be six weeks of border protests.

Earlier on Tuesday, the international group Human Rights Watch accused Lieberman and other senior officials of "unlawfully" calling for the use of live fire against Palestinian protesters who posed no imminent threat to life.

Lieberman signalled defiance, saying that "we have established clear ground rules and we do not intend to change them. "

Palestinian health officials say more than 750 Palestinians were wounded by army fire Friday.
