Palestinians buried the dead yesterday from the bloodiest day in Gaza in years, after Israeli forces killed 60 Palestinians near the Gaza-Israel border during demonstrations against the opening of the US embassy in Jerusalem.

Israeli forces shot dead at least two more Palestinians yesterday, although protests were quieter than the previous day, reported Reuters. It appeared that many protesters had gone to mourning tents rather than back to the scene of Monday's bloodshed. Mourners marched through the strip, waving Palestinian flags and calling for revenge.

"With souls and blood we redeem you martyrs," they shouted.

Meanwhile, Israel came under mounting international pressure yesterday amid calls for an independent probe over the killings.

Palestinians yesterday marked the Nakba, or "catastrophe", commemorating the more than 700,000 Palestinians who fled or were expelled in the 1948 war surrounding Israel's creation.

Most of the 60 Gazans killed Monday were shot by Israeli snipers, the Gaza health ministry said.

The toll included a baby who died from tear gas inhalation along with eight other children under the age of 16, the ministry said.

In the bloodiest day of the Israeli-Palestinian conflict since the 2014 Gaza war, at least 2,400 other Palestinians were wounded.

There were numerous calls for an independent investigation into the deaths, with Britain, Germany, Switzerland and Belgium among those supporting such action.

UN Secretary-General Antonio Guterres and the European Union have previously called for an independent probe, with 116 Palestinians killed by Israeli forces since a campaign of protests on the Gaza-Israel border was launched on March 30.

Only one Israeli soldier has been reported wounded during that time.

British Prime Minister Theresa May called for restraint, saying "such violence is destructive to peace efforts".

French President Emmanuel Macron condemned the "violence of the Israeli armed forces against the protesters".

Ireland and Belgium summoned the Israeli envoys in their capitals, while South Africa recalled its ambassador to Israel.

Turkey has told Israel's ambassador to temporarily leave the country, while President Recep Tayyip Erdogan accused Israel of "state terror" and "genocide".

Israeli Prime Minister Benjamin Netanyahu hit back at Erdogan, saying that as a leading supporter of Palestinian Islamist group Hamas "there's no doubt he's an expert on terror and slaughter."

Israel yesterday ordered the Turkish consul in Jerusalem to leave for an unspecified period of time, its foreign ministry said.

Responding to the Israel premier on Twitter, Erdogan further sharpened his language, saying "Netanyahu is the PM of an apartheid state that has occupied a defenceless people's lands for 60+ yrs in violation of UN resolutions."

"He has the blood of Palestinians on his hands and can't cover up crimes by attacking Turkey," Erdogan added.

At talks with British Premier Theresa May, Erdogan said the United States had "paved the way... and laid the foundations" for the killings with its embassy move.

Erdogan also vowed to send a "strong message" to the world through a planned summit of Organisation of Islamic Cooperation (OIC).

Meanwhile, Palestinian president Mahmud Abbas withdrew his top representative to the United States yesterday, the foreign ministry announced, a day after the US moved its Israeli embassy to Jerusalem.

The US ambassador to the United Nations strongly defended Israel at an emergency meeting of the UN Security Council on the violence in Gaza.

"No country in this chamber would act with more restraint than Israel has," Nikki Haley said. "In fact the records of several countries here today suggest they would be much less restrained."

The United States has blocked the adoption of a Security Council statement that would have called for an independent probe into the violence, diplomats said.

Some funerals were held in the Israeli-blockaded Gaza Strip on Monday, while others took place yesterday.

Hundreds attended the funeral of Yazan Tubasi, 23, killed east of Gaza City.

"I am happy that my son is a martyr," said his father Ibrahim, 50, though he was crying uncontrollably.

In the West Bank, Abbas declared a general strike yesterday after accusing Israel of "massacres".

Despite the bloodshed, the embassy inauguration on Monday went ahead as planned in Jerusalem, attended by a Washington delegation that included US President Donald Trump's daughter Ivanka and her husband Jared Kushner, both White House aides.

Israel's military said 40,000 Gazans took part in the protests the same day.

It said its aircraft had targeted 11 Hamas sites and tanks fired at "two terror posts belonging to Hamas", accusing the Islamist movement of opening fire towards Israeli forces.

Israel says its action is necessary to stop infiltrations of the border fence and claims that Hamas uses the protests as cover to carry out violence.

The embassy inauguration -- which took place on the 70th anniversary of Israel's founding -- followed Trump's December 6 recognition of Jerusalem as Israel's capital.

Israel occupied the West Bank and east Jerusalem in 1967 and later annexed east Jerusalem in a move never recognised by the international community. Israel considers the entire city its capital, while the Palestinians see east Jerusalem as the capital of their future state.
