Palestinian militant groups threatened punishment on Thursday for "collaborators" furthering Israeli goals after the first substantial protests against the war in Gaza and Hamas' rule.

Palestinians took part in the largest anti-Hamas protests in Gaza since the war with Israel began. It's a rare show of discontent by the citizens of the war-torn territory.

Thousands of Palestinians demonstrated across parts of the Gaza Strip Wednesday in rare protests against militant group Hamas, the ruler of the war-ravaged territory.
