(Cairo) -- Troops are moving through the streets of Cairo after a deadline came and went for President Mohamed Mursi to share power. A national security adviser says a military coup is underway. The city's main square is jammed full of demonstrators. Mursi held fast yesterday, saying he would not leave office.
Meantime, U.S. oil prices are at a 14-month high above 100 dollars a barrel. There's fear that continuing unrest in Egypt could lead to a supply disruption. Egypt is the Arab world's most populous nation.
