Palestinian deputy prime minister said on Monday that reconstruction in Gaza after the war, will cost at least $6 billion. "Once a ceasefire is reached, we will have to tackle the immediate problem of rehousing those who lost their homes," Mohammed Mustafa said. "According to our estimates, they may number 400,000 people."

"There is a need to build 100,000 housing units," Mustafa said, adding that a Palestinian government committee has begun assessing the damage and the $6 billion figure was only an initial estimate.
