Funerals are to take place on Tuesday for Palestinians killed in protests in Gaza that coincided with the US opening its embassy in Israel in Jerusalem.
On Monday, the deadliest day in Gaza since 2014, 60 people including eight children died after Israeli troops opened fire with live ammunition and used tear gas on the Gaza border.
The death toll rose on Tuesday after another child succumbed to their injuries. Meanwhile, 2,771 people were injured, according to Gaza's Health Ministry.
Palestinian President Mahmoud Abbas described Monday's events as a "massacre," but Israeli Prime Minister Benjamin Netanyahu said "every country has an obligation to defend its borders."
As the protests took place, 100 kilometers away the US was opening its embassy in Jerusalem, in a ceremony attended by President Donald Trump's daughter Ivanka and her husband Jared Kushner.

Trump addressed the ceremony via videolink, and tweeted to say it was a "big day for Israel."
Fresh protests are expected on Tuesday for Nakba Day, or Catastrophe Day, which commemorates the 700,000 Palestinians who were forced to leave their homes in the war that followed the state of Israel being created. A general strike that usually takes place across East Jerusalem and the West Bank is expected to be widely observed widely this year, to mark 70 years since Nakba.
Monday's protests were the culmination of seven weeks of demonstrations by Palestinians, dubbed the "Great March of Return." They have been in part organised by Hamas, which is the ruling authority in Gaza and has called for Israel's destruction.
"The Hamas terrorist organisation declares its intention to destroy Israel and sends thousands to breach the border fence in order to achieve this goal," Israeli Prime Minister Netanyahu said. "We will continue to act with determination to protect our sovereignty and our citizens."

Israel said up to 40,000 people gathered along the Gaza side of the border during this week's protest, and blamed Hamas for putting civilians in harm's way.
"The decision is in the hands of Hamas," Yaakov Amidror, a former national security adviser and now a senior fellow at the Jerusalem Institute for Strategic Studies, told BuzzFeed News, when asked whether violence would escalate again Tuesday.
Asked whether the Israeli troops had used excessive force, he said: "There is no way to identify who is who and this is why Hamas is using these civilians... to cover its terrorist actions and attempt to destroy the barrier that we are building."
Khalil al-Hayya, a Hamas political bureau member, said in a statement that "the shedding of our people’s blood today stains the faces of those normalizing with the Israeli Occupation and bargaining on the Palestinian cause with shame."
Referring to the Jerusalem embassy move, he said: "The American administration bears all the consequences of the implementation of this unjust decision, and this terrible crime will not pass unaccountable."

Israel's ambassador to the UK, Mark Regev, defended the army's actions in an interview with BBC Radio 4's Today programme.
He said Israel "didn't want to see this violence," and had dropped leaflets urging people not to go to the border, and had put the same message out on social media, radio and TV.
"We used live fire in only a very measured way in a very surgical way and only when there is no alternative," he said. "You had some 40,000 people yesterday involved in violent riots on our border. There were continuous attempts to storm the border and breach the border. We have to protect our people. If we allow the Hamas terrorists to enter Israel we will have dead Israelis. We must protect our border."
The Israel Defense Forces (IDF) said it struck 13 "terror targets" belonging to Hamas in Gaza yesterday, and that throughout the day "many rioters attempted to infiltrate Israel."
The IDF will continue to prevent mass terror attacks, which have largely been orchestrated by the Hamas terror organization. All terror activity will be met with a harsh response. IDF troops will continue to defend Israel & its civilians10:47 PM - 14 May 2018
The IDF said that in Monday's demonstrations protesters used around 10 explosive devices and several firebombs, while "numerous" shots were fired.
But Israel's actions were roundly condemned as being excessive, as the international community called for restraint.
Turkish President Reccep Tayip Erdogan blamed President Trump and Netanyahu for the deaths.
"There are two people responsible. Mr Trump and Netanyahu," he said in an interview with Bloomberg.
UK Foreign Secretary Boris Johnson expressed concern over the violence, saying Britain was "extremely saddened by the loss of life that has taken place and we understand that some have been provoking that violence but on the other hand there has got to be restraint in the use of live rounds."
He added: "The UK position is that we don't agree with the US decision to move the embassy and we continue to believe that is playing the wrong card at the wrong time. But we remain absolutely committed to a two-state solution."

The Office of the United Nations High Commissioner for Human Rights said it condemned the violence in Gaza.
#Gaza: @UNHumanRights extremely worried about what may happen today -- an emotional day on all sides -- and in the weeks ahead. We urge maximum restraint. Enough is enough.09:00 AM - 15 May 2018
Médecins Sans Frontières, an aid agency treating the wounded in Gaza, said what had happened in Gaza was "unacceptable and inhuman."
"This bloodbath is the continuation of Israeli army’s policy during the last seven weeks: shooting with live ammunition at demonstrators, on the assumption that anyone approaching the separation fence is a legitimate target. Most of the wounded will be condemned to suffer lifelong injuries," said Marie-Elisabeth Ingres, the MSF representative in Gaza.
And United Nations Secretary-General Antonio Guterres said he was "profoundly alarmed and concerned" by the escalation of violence, and urged restraint on both sides.
I am profoundly alarmed and concerned by the sharp escalation of violence and the number of Palestinians killed and injured in the Gaza protests. It is imperative that everyone shows the utmost restraint to avoid further loss of life.07:30 AM - 15 May 2018
But despite similar criticism from France and Germany, White House spokesperson Raj Shah said: "The responsibility for these tragic deaths rests squarely with Hamas."
