He was among at least 131 Palestinians wounded by Israeli bullets during Friday's protests, even as an informal truce agreed after a deadly flare-up between Hamas and the Israeli Army largely held, AFP reported.
The Health Ministry identified the dead man as Ahmed Abu Lulu and said he was shot in east of the southern city of Rafah where two other Palestinians were also killed.
The ministry identified them as Ali al-Alul, 55, and volunteer medic Abdullah al-Qatati, 21.
A few thousand protesters had gathered in different locations along the buffer zone.
The Israeli Army said a grenade was thrown at troops near the fence with northern Gaza without causing any casualties. It said troops responded with tank fire against two Hamas posts.
But the region was otherwise calm after a deal to end all rocket fire into Israel and airstrikes on the Gaza Strip appeared to go into effect around midnight (2100 GMT) on Thursday.
There was no official confirmation from Israel or Hamas but there were no fresh airstrikes on Friday.
Thursday had seen extensive Israeli raids in retaliation for the launching of more than 180 rockets and mortar rounds by Hamas on Wednesday night.
It was one of the most serious escalations since the 2014 Gaza war and followed months of rising tensions.
Three Palestinians were killed in the Israeli strikes, including a pregnant woman and her 18-month-old daughter. Seven Israelis were wounded by Palestinian rocket fire.
The European Union said Gaza and Israel were “dangerously close” to a new conflict and called for urgent de-escalation to keep civilians from further risk.
At least 168 Palestinians have been killed since the protests in Gaza began on March 30.
Most were killed by Israeli fire during the protests but others died in airstrikes.
One Israeli soldier was shot dead by a Palestinian sniper.
