Funeral of a 21-year-old medic shot and killed as she was trying to give aid to a protester drew thousands of Palestinians on Saturday.
Early Sunday, the Israeli military said fighter jets attacked three Hamas military compounds in response to the rocket fire.
It's understood at least three Hamas sites were hit. Its resolution had initially called for an worldwide protection mission for Palestinians, but this was dropped in favor of just condemning Israel force against civilians - which also failed.
There were no immediate reports of casualties in any of the incidents. In the protests, billed as the "Great March of Return", Palestinians have been calling for the right to return to lands lost to Israel during the 1948 war of its creation.
Israel's Iron Done defense system intercepted some and others landed in Gaza.
Witnesses say she was shot dead by an Israeli sniper, and her father displayed her blood-soaked medical vest with a bullet hole.
On the same day the USA vetoed a resolution at the U.N Security Council demanding an end to Israel's practice of firing on unarmed demonstrators in the Occupied Palestinian Territories and the Gaza strip, outrage was again heightened after a nurse attempting to attend to injured protesters was shot and killed by IDF snipers near the Gaza border.
After Najjar's funeral, dozens of mourners headed to the fence and started throwing stones at the Israeli soldiers on the other side.
They peaked on 14 May when at least 61 Palestinians were killed in clashes as tens of thousands of Gazans protested the U.S. transfer of its embassy in Israel to Jerusalem the same day.
According to Gaza's health ministry, at least 60 people died during the protests.
Health ministry spokesman Ashraf al-Qudra told The Times of Israel that this brings the death toll of people killed by the IDF to 123, according to a count by the ministry.
Low-level demonstrations have continued since.
On May 14, the same day the United States opened its controversial new embassy in Jerusalem, tens of thousands of Palestinians demonstrated in the Gaza Strip.
Earlier this week, in response to a barrage of rockets fired into civilian areas of Israel, the United States called for an emergency meeting of the Security Council, where many Council ambassadors criticized Hamas and Islamic Jihad for the action.
Egyptian mediation efforts successfully restored the cease-fire that has largely held since the end of a 50-day war between Israel and Gaza resistance groups in 2014.
