Israeli forces have killed three Palestinian men along the border with the Gaza Strip.
Israel's military said the three were militants but relatives identified them as fishermen.
The military released a statement saying soldiers fired on the men after they were spotted planting an explosive device in a no-go zone along the border between 2am and 3am.
A spokesman for the Gaza health ministry, Adham Abu Salmiya, said they were killed by Israeli fire near the Mediterranean shore in northern Gaza. They were in their 20s and were wearing civilian clothing, he said.
Relatives who came to the hospital to receive the bodies for burial said they were fishermen. None of Gaza's armed groups immediately claimed the men as members.
The military maintains a buffer zone along the border fence, where militants have planted bombs targeting Israeli forces in the past.
Gaza is controlled by the Islamic militant group Hamas. Bloodshed in the territory has decreased since Israel's military offensive in Gaza just over two years ago, but rocket fire and border clashes have continued.
