Al-Jazeera Video: Besieged Gaza denied water

"Israel's blockade of the Gaza Strip has brought immense sufferings to Palestinians living in the coastal territory. The siege even impedes the supply of water, the most basic need for human survival.

Now - 80 per cent of Gazans lack access to clean water.

The head of Gaza's water authority says he has plans and the means to import water from other countries until self-dependency is reached, but Israel's blockade is the only thing in the way.
