The Gaza Health Ministry says the Palestinian death toll in Gaza border protests has risen to 58, including 57 people killed by Israeli army fire and a baby who died from tear gas inhalation.
The ministry says six of those killed by gunshots were minors.
It says more than 2,700 people were injured Monday, including 1,360 by live fire. Of the wounded, 130 are in serious or critical condition.
The ministry did not say how the baby was exposed to tear gas.
On Monday, tens of thousands of Palestinians rallied near Israel's border fence to protest a blockade of their territory and the move of the US Embassy to contested Jerusalem that day.
It was the deadliest day in Gaza since a 2014 war between Israel and Gaza's ruling Hamas..
