Hospital officials say Palestinians sheltering in tents or seeking scarce food aid were among at least 25 people killed by Israeli strikes in Gaza.

The world's leading authority on food crises says the Gaza Strip’s largest city is gripped by famine, and that it is likely to spread without an immediate ceasefire and an end to restrictions on humanitarian aid.

Aid groups however say that aid is still insufficient. Secretary of State for International Development Randeep Sarai says Ottawa is deeply alarmed by the horrific deteriorating conditions in Gaza and says Israel, as the occupying power, is failing to live up to its obligations under international law.
