Israel should consider cutting its supply of electricity to the Gaza Strip this summer if it experiences power shortages, Israeli Environment Minister Gilad Erdan said on Sunday.

Erdan, a member of Prime Minister Benjamin Netanyahu's right-wing Likud party, outlined the proposal in a letter to ministers, who were scheduled to discuss the issue in their Sunday cabinet meeting.

U.N. chief Ban Ki-moon urged Israel to try or release hunger-striking Palestinian prisoners after activists denounced his "silence" in a protest outside the U.N.'s West Bank offices.

The Israeli navy has recently strengthened its “indirect cooperation” with the Lebanese navy in the Mediterranean ahead of possible pro-Palestinian flotillas to Gaza on Nakba Day, Haaretz daily reported.
