Salafist jihadi groups test fired a long range rocket in the Sinai Peninsula, an Egyptian military official told Egyptian state TV on Sunday.

The official said the rocket launch was part of exercises being held by jihadi groups in the peninsula, and that the rocket was in fact Israeli ordnance that had been collected by Bedouin. Bedouin are known to scavenge areas where the IDF practices drills, or have been stationed in search of munitions to sell, often to terrorist groups who then deploy those arms against the IDF and Egyptian security forces.

According to the military official, the rocket was fired toward an unoccupied area in central Sinai, and its explosion caused a three-meter (10-feet) deep crater.

Meanwhile, tensions across Egypt appeared to subside on Sunday after a week of violent protests. Egyptian Interior Minster Mohamed Ibrahim accused the Egyptian opposition of inciting the public to violent protests and held them responsible for demonstrators' deaths.

"A political battle is being waged on the backs of the protesters, and reckless politicians are encouraging violent riots," Ibrahim said. "Our police forces are working under almost impossible conditions trying to mediate between the opposing sides and allow freedom of speech in a non-violent framework."

Egyptian media outlets reported on Sunday that Egyptian President Mohammed Morsi held an emergency meeting regarding the country's financial collapse and the expected fallout. Egyptian intelligence and preventative security have begun preparing for an outbreak of violent civil unrest if the Egyptian public is unable to cope with the depressed economy. Egyptian outlets reported that the Egyptian pound's continued devaluation has increased the prices of basic goods. Gas and oil prices have skyrocketed. The weakening Egyptian pound has also caused a spike in inflation at a rate of more than 8 percent.

Die-hard Egyptian soccer fans rampaged through the heart of Cairo on Saturday, furious that seven police officers were acquitted while death sentences were confirmed against 21 people in the trial over the Feb. 1, 2012, stadium riot that left 74 people dead.

The stadium riot, which occurred in the city of Port Said at the northern tip of the Suez Canal, has taken on political undertones both because police faced allegations of negligence and because the verdicts were announced at a time when Egypt is gripped by the latest and most serious bout of political turmoil in the two years since Hosni Mubarak was ousted.

The verdicts were handed down against the backdrop of an unprecedented wave of strikes by the nation's police force over demands for better working conditions and anger over what many believe are attempts by Morsi and the Muslim Brotherhood to take control of the police force.

Tensions over the riot — which began when supporters of Port Said's Al-Masry club set upon fans of Cairo's Al-Ahly club after the final whistle of a league game that the home team won — have fueled some of the deadliest street violence in months. Police guarding the stadium, meanwhile, faced allegations ranging from not having searched people entering the stadium to failing to intervene to stop the bloodshed.
