(CNN) - The US officially relocated its embassy to Jerusalem on Monday, formally upending decades of American foreign policy in a move that was met with clashes and protests along the Gaza-Israeli border.
Here is what we know:
At least 58 Palestinians were killed by Israeli forces during Monday and Tuesday clashes, according to the Palestinian Ministry of Health.
Israeli soldiers have killed more than 100 people since the latest wave of protests began in March, according to a CNN count based on the Palestinian Ministry of Health figures.
The dead include 8-month-old Laila Anwar Ghandour, who died of tear-gas asphyxiation, the Ministry of Health said. Most of the dead were killed by Israeli fire near the border.
More than 2,700 people suffered injuries, according to the Palestinian officials.
Monday's death toll was the biggest number of fatalities suffered in one day since the latest round of demonstrations began more than six weeks ago. The previous high was 17, which happened on the day the protests started on March 30.
Around 35,000 people -- who the Israel Defense Forces describes as "violent rioters" -- assembled in 12 locations along the border fence separating Gaza and Israel, according to the IDF.
Thousands more were gathered in a tent city about a kilometer from the border.
The military said protesters threw Molotov cocktails, burned tires and threw stones at Israeli soldiers along the fence.
An Israeli jet struck five targets in a "military training facility belonging to Hamas" in northern Gaza on Monday, the Israeli military said.
While Gaza has seen the majority of the violence, protesters are facing off with Israeli authorities in the West Bank as well, but there were no deaths reported there Monday.
The Pentagon, in conjunction with the US State Department, has increased Marine Corps security forces at a number of US embassies in the Middle East and Africa in light of the unrest, according to several military officials.

Trump announced the decision to move the embassy in December, when he formally recognized Jerusalem as the capital of Israel. It marked the fulfillment of a campaign promise he made to the pro-Israel group American Israel Public Affairs Committee.
The embassy move is contentious for Palestinians, who hope to claim part of the city as their future capital, and for many in the Arab world, as it is home to some of the holiest sites in Islam. The city also is home to holy sites for Jews and Christians.
In 1995, Congress passed a law requiring America to move its embassy from Tel Aviv to Jerusalem, but every president since then has declined to make the move, citing national security interests.
The State Department noted that the opening takes place on the 70th anniversary of American recognition of the Israeli state, the day of its founding and a day Palestinians refer to as "The Catastrophe," referring to the hundreds of thousands of people who were expelled from, or fled, their homes during the war that surrounded the foundation of Israel.
