On Sunday, at least 51 people were killed and more than 260 were injured in Egypt during clashes between protesters supportive of ousted Islamist President Morsi and backers of the Egyptian military. The protests, the deadliest since hundreds were killed on August 14, took place on an Egyptian national holiday honoring the 40th anniversary of the Arab-Israeli War.
