Egypt's Great Pyramid bathed in national colours of victims
The Great Pyramid of Khufu, the only one of the Seven Wonders of the ancient world still standing, was illuminated by projectors reproducing the flags of France and Russia and the green cedar of Lebanon.
Young Egyptians were staging an overnight candle-lit vigil at the foot of the more than 4,500-year-old giant monument on the Giza plateau on the outskirts of Cairo.
The tourism and antiquities ministries organised the ceremony to "mourn the innocent lives lost around the world", paying tribute "to the victims of the crash of the Russian airplane and attacks in Lebanon and France".
Late Friday, gun and bomb attacks in Paris claimed by the Islamic State group killed 129 people and wounded 350.
On Thursday in Beirut, twin bombings claimed by IS killed 44 people in southern Beirut, a stronghold of the Shiite Hezbollah organisation that backs the embattled Syrian regime.
Elsewhere in the Gulf, Kuwait City's landmark towers were also illuminated in the red, white and blue of France.
