On Tuesday, the Israeli Army released a video that appeared to show protesters detonating several explosions near the border.
The opening of the U.S. Embassy on Monday was met with mass protests on the Gaza border, where Israeli troops killed almost 60 Palestinians and over 2,000 others, triggering a wave of worldwide condemnation.
Seething over a perceived USA betrayal on Jerusalem, Abbas is preparing to pursue a war crimes complaint against Israel at the International Criminal Court that would sharply escalate tensions with Israel.
Organizers say the wave of border protests is meant in large part to break a decade-old blockade imposed by Israel and Egypt and pressure Israel to ease its restrictions.
He said an worldwide commission should investigate the Gaza violence and that "Israel should account for its actions".
U.S. Ambassador to the U.N. Nikki Haley also blamed Hamas for the violence, saying, "Let's remember that the Hamas terrorist organization has been inciting violence for years, long before the United States made a decision to move our embassy".
Israeli security forces said they were responding to deliberate attempts, spurred by Hamas, to overwhelm and breach the boundary fence to launch terror attacks in Israel.

Guatemalan President Jimmy Morales and Israeli Prime Minister Benjamin Netanyahu attended the embassy's opening on Wednesday in an office complex in west Jerusalem. But a Hamas senior official confessed in a television interview Wednesday that some 50 of the 62 people who died Monday and Tuesday were Hamas members.
"The responsibility for these tragic deaths rests squarely with Hamas", Deputy Press Secretary Raj Shah said.
Morales called it a "transcendental moment for future generations" who will "remember that friendly countries took courageous decisions in favour of Israel and we do this because you have a special place in our hearts". "Therefore we consider the participation in this event a contradiction to such values", said Amal Jadou, a Palestinian Foreign Ministry official. In Geneva, the United Nations human rights office said Israel has repeatedly violated global norms by using deadly live fire to repel protesters.
Most countries keep their embassies in Tel Aviv, however, saying the status of the holy city should be decided in peace talks between Israel and Palestinians, which want to have their own capital there.
"They incite people to violence, place as many civilians as possible in the line of fire to maximise civilian casualties, then they blame Israel and come to the United Nations to complain. And Israel is in a very hard situation, when probably large numbers of people want to enter Israel from a place that has been threatening Israel for some years now", Hoyer said to The Intercept.
Palestinian Foreign Minister Riad Malki said Wednesday that he has asked the ICC for an appointment to deliver a "state party referral" of a case against Israel.
Israel accuses Hamas, with whom it has fought three wars since 2008, of seeking to use the demonstrations as cover for violence.
The violence coincided with the opening of the U.S. Embassy in the contested city of Jerusalem.
