A new program for getting desperately needed food into the hands of starving Palestinians in Gaza is only days old, but it’s already mired in chaos and tragedy.

Dozens of Palestinians have been killed in two separate incidents, according to Gaza officials, after Israel said its forces opened fire.

The Gaza Humanitarian Foundation started distributing aid this week, but it was off to a rough start as desperate Palestinians scrambled to get food after weeks of delays. The group denies any reports of violence and says it will push forward with opening more distribution points in the strip.
