Hundreds of mourners on Sunday buried two Gaza fishermen shot dead at sea, as the Palestinian fishing union demanded an investigation.
Three brothers were fishing on Friday in the Mediterranean Sea off the Gaza Strip, a crowded sliver of land sandwiched between Egypt and Israel, when their boat was hit by gunfire.
Two died and their bodies were returned to Gaza by Egyptian forces, the union said, while the third brother was wounded and remains in Egypt.
A spokesman of the Palestinian Ministry of Interior in Gaza on Friday said his authorities had been looking into the reported disappearance of three fishermen.
Hamas, the Palestinian militant group ruling Gaza, has called on Egypt to investigate the incident, condemning it as violence.
"There is no justification for the repeated violent treatment against those who seek to eke out a living for their children," said a Hamas statement.
Later on Saturday, Palestinian Prime Minister Mohamed Shtayyeh mourned the death of the fishermen.
"It is a sad day for our people. It is with a lot of pain that we mourn the two young fishermen Mahmoud and Hassan al-Zaazou, martyrs of breadwinning," he said in a statement quoted by local media.
