Two days after aid began entering Gaza, the desperately needed new supplies have not yet reached people in Gaza, which has been under an Israeli blockade for nearly three months, according to the United Nations.

Britain, France and Canada called the Israeli plans for escalation “disproportionate” and “egregious” at a time when the U.N. is warning the population is at risk of famine.

An estimated 14,000 babies could die without essential aid according to the U.N. as Israel military operations intensify.
