A video has emerged of the moment a 13-floor residential tower block collapsed in Gaza following an Israeli airstrike.
Initial reports suggested 17 people were injured.
The Israeli military said the building had been used as a command centre by Hamas. Local residents said it housed 44 families.
A number of immediate steps have been agreed, while more complex issues will be addressed in further talks set to begin within a month.
After the success of the Ice Bucket Challenge, the people of Gaza are using rubble and dirt instead of cold water to highlight their plight.
