Neither Emirati nor Israeli officials have provided any details about the circumstances of Kogan's murder.

International humanitarian NGO Danish Refugee Council warned on Monday that Gazans are at long-term risk from unexploded and unused ordnance in the densely populated Palestinian territory.

Cristiano Ronaldo struck twice for Al Nassr as they continued to thrive in the AFC Champions League Elite, with the Saudi champions defeating Al Gharafa 3-1 in Qatar on Monday.

The 39-year-old helped move Al Nassr to the brink of the last 16 in Asia's premier continental club competition, needing just two points from their final three group games.

Only Al Shorta, who have two points with four games to play, can deny Ronaldo's side a place in the next round, after Persepolis drew 1-1 at Al Rayyan.

With an intensive Israeli military operation in Gaza's besieged north in its 50th day, remaining residents are left "scavenging among the rubble" for food, UNRWA spokeswoman Louise Wateridge told AFP.

Egyptian authorities said more than a dozen people, mostly foreigners, were still missing after a tourist yacht capsized in the Red Sea on Monday, with 28 others rescued.

The vessel carrying 31 tourists of various nationalities and a 13-member crew sent out a distress call at 5:30 am (0330 GMT), a statement from Egypt's Red Sea governorate said.

It said 16 people are missing -- 12 foreigners and four Egyptians -- revising an earlier figure of 17 missing.

The statement said the boat, the "Sea Story", is owned by an Egyptian national.

The United States, European Union and United Nations have all pushed in recent days for a truce in the long-running hostilities between Israel and Hezbollah, which flared into all-out war in late September.

Israel on Monday held an emotional farewell ceremony for an Israeli rabbi killed in the United Arab Emirates, after Emirati authorities said three suspects from Uzbekistan were in custody over his murder.

Israeli strikes pummelled south Beirut on Monday, Lebanese official media said, and health authorities reported 31 people killed across the war-hit country, most of them in the south.
