More violence was expected amid simmering tensions last night on the day that marked the 70th anniversary of the start of the first war between the newly created Jewish state and its Arab neighbours in 1948.
Monday's violence erupted after up to 40,000 protestors gathered at three crossing points in the security fence which separates the Hamascontrolled Gaza Strip from Israel.
Since the protests began on March 30, Israeli forces have killed at least 109 Palestinians in the coastal enclave and wounded about 12,000 people.
The baby's body was wrapped in a Palestinian flag and buried on Tuesday.
At least 61 people were killed on Monday and more than 2,400 injured after Israeli forces gunned down Palestinians protesting against the U.S. embassy move to Jerusalem.
In preparation for a further wave of protests, tanks rolled in and sharpshooters took up positions on the Israeli side of the border.
The family prefers to focus on who fired the gas rather than the series of decisions that led to a baby being a few hundred metres from the Israeli border during the protests and clashes.
"We are talking about 25 times the capacity of the emergency department, with all the big challenges and the shortage of medicine and medical supplies that has reached critical levels", Ayman Al Sahabani told Reuters.
Dozens of injured Palestinians are still waiting for surgery at Gaza's main hospital, where patients with gunshot wounds filled wards and hallways.
More than 2,700 people were injured, many of whom were shot in the legs, in events described by Palestinian leaders as a "massacre" but which the Israelis said was a "measured" response to threatened terrorism by the militant Palestinian group Hamas. Doctors told Al Jazeera that al-Maqal would likely succumb to his injuries if he does not undergo additional surgery.
According to The Independent, it remains unclear how near the infant was to the protest area.
Eight-month-old Leila al-Ghandour was exposed to the gas during major protests yesterday, in which the health ministry said 58 Palestinians were killed.
Tens of people attended the funeral of Laila al-Ghandour, who died of tear gas inhalation late on Monday.
In addition, Israeli drones fired gas bombs at the tents of the Return Camp, including medical tents, in Khuza'a town, east of the southern Gaza Strip city of Khan Younis.
