KHUZAA, Gaza Strip — Thousands of Palestinians, including hundreds of medical workers in white uniforms, took part Saturday in the funeral procession of a colleague who was shot dead by Israeli troops the previous day along the Israel-Gaza border.

Relatives say 21-year-old Razan Najjar was a volunteer paramedic who had helped evacuate and treat the wounded during weeks of cross-border violence. She is just the second female fatality out of more than 115 killed since the deadly border protest campaign began in late March.

After the funeral, dozens of mourners headed to the fence and started throwing stones at the Israeli soldiers on the other side. The Palestinian Health Ministry said five protesters were wounded by Israeli fire.

Later Saturday, in a development that threatens to collapse an informal cease-fire, the Israeli military said two projectiles were fired from Gaza. One was intercepted by the Iron Dome defense system and the other landed inside Gaza. Earlier this week, Gaza militants fired a large barrage at Israel, which responded with heavy strikes against Gaza installations.

Meanwhile, in the West Bank, the Israeli military said its troops shot dead a Palestinian who tried to ram a tractor into its forces.

The military said its initial investigation revealed that a 35-year-old Palestinian from a village near Hebron tried to run over an officer with a Bobcat tractor. The attacker then turned around and tried to attack nearby Israeli civilians, the military said.

It said a soldier opened fire, killing the assailant. No Israeli troops were harmed.

Since 2015, Palestinians have killed over 50 Israelis, two visiting Americans and a British tourist in stabbings, shootings and car-ramming attacks. Over 260 Palestinians were killed by Israeli forces in that time. Israel says most were attackers. The attacks have petered off in recent months as the Palestinian focus has shifted toward mass protests at the Gaza border.

On Friday, the Palestinians protested for the 10th week in a row. The military said some hurled grenades and pipe bombs at troops behind the security fence. Some 40 Palestinians were wounded and Najjar was the only one killed.
