Heavy rains over the past week have compounded the already dire living conditions of the hundreds of thousands of displaced Palestinians in the Gaza Strip, UN agencies say, BBC reported.
Unicef spokesman Jonathan Crickx told the BBC that the weather overnight had been "horrendous", with the rain so intense that he had seen up to 15cm (6in) of water on the ground near his office.
He said he was extremely concerned that children living in tents and makeshift shelters in wet clothing would succumb to hypothermia and other illnesses, according to BBC.
