Debris from EgyptAir flight 804, which crashed into the Mediterranean Sea in May, washed up on Israel’s coast for the second time in less than a month, Israeli media reported.
The debris, including apparently part of the plane's tail, appeared on the shore of the coastal town of Haifa, local Channel 2 television news said.
Police officers in Haifa contacted the foreign ministry, which will hand over the fragments of the plane to Egypt.
Egyptian investigators have yet to determine the cause of the incident on 19 May, when the Airbus A320 crashed into the Mediterranean while en route from Paris to Cairo, killing all 66 people on board.
Investigators have said the plane's wreckage, identified in the central Mediterranean, showed signs of fire, while a data recorder has suggested that smoke had been detected on board.
Three weeks ago, aircraft parts believed to belong to the lost plane were found in Netanya, a Mediterranean resort town north of Tel Aviv, and were delivered to Egypt shortly after.
A New York Times report on Saturday quoted anonymous Egyptian officials as saying that the flight likely broke up in midair after a fire erupted in or near the cockpit. They said it remains unclear whether the blaze was triggered by mechanical malfunction or a criminal act.
There was no official confirmation of the latest conclusion.
