Quarter of Gaza population displaced, says UN

Israel will not stop its operation in Gaza until all the tunnels constructed by Hamas have been destroyed, PM Benjamin Netanyahu has said.

Speaking ahead of a cabinet meeting, he said Israel was determined to destroy the tunnels - used to attack troops and towns - "with or without a ceasefire".

Meanwhile the UN says it is sheltering 225,178 Palestinians in 86 shelters across Gaza, with 200,000 more thought to be staying with friends or family.

The total number displaced amounts to 25% of all of Gaza's 1.7 million inhabitants.
