Tom Fletcher says five aid trucks allowed into Gaza yesterday have not yet reached people, as the UK, France and Canada threaten action against Israel.

The prime minister said that while Israel plans to take “all” of Gaza, he had to prevent mass starvation there for “practical and diplomatic reasons.”

Despite the announcement, no aid had entered Gaza by mid-afternoon Monday. Aid trucks that were briefly parked on the Israeli side of a border crossing turned back and drove away.

Hundreds of Palestinians have been killed in recent days as Israel has intensified air strikes, the Hamas-run health ministry says.

Israel launched an extensive ground operation in Gaza Sunday in addition to an intense air campaign that health officials in the territory say killed over 100 people overnight and shuttered the last functioning hospital in the enclave’s north.
