"Hundreds of Palestinians were evacuated from their homes Sunday morning after Israeli authorities opened a number of dams near the border, flooding the Gaza Valley in the wake of a recent severe winter storm.
Israeli dams on the river to collect rainwater have dried up the wetlands inside Gaza, and destroyed the only source of surface water in the area.
The chief of the civil defence agency in Gaza told Al Jazeera: "Israel opened water dams, without warning, last night, causing serious damage to Gazan villages near the border. More than 40 homes were flooded and 80 families are currently in shelters as a result."
Over a hundred thousand Gazans lost their home in the fire-bombing of Gaza last year.
