A Palestinian medic was killed by Israeli fire during clashes and protests along the Gaza border today, the health ministry in the enclave said.
But an unofficial ceasefire agreement between the two foes went into effect around midnight (2100 GMT) yesterday.
This evening a few thousand Palestinians gathered along the border for weekly protests.
Qatati, who was in his 20s and a volunteer with the government medical services, was shot in the chest east of Rafah in southern Gaza, a health ministry spokesman told AFP.
He said another 25 Palestinians were hit by Israeli fire, with one in critical condition after being shot in the head.
Qatati is at least the second medic to have been killed by Israeli fire during months of border protests.
The protesters, who gathered in different locations along the Israel border, set tyres ablaze and threw stones but there were fewer people demonstrating that in previous weeks, AFP correspondents said.
The Israeli army said a few thousand "rioters" gathered in a number of sites along the border, with soldiers using riot dispersal means, including live fire. Three Palestinians were killed in the Israeli strikes, while seven Israelis were wounded by Palestinian rocket fire.
It was one of the most serious flareups since the 2014 Gaza war and followed months of escalating tensions.
