U.S.-Iran extend shaky ceasefire but significant challenges still remain

VIDEO: The United States and Iran reached an initial agreement Monday that would extend their shaky ceasefire and lead to the reopening of the Strait of Hormuz, but significant challenges remain to ending the war, including whether Israel will continue it’s offensive in Lebanon. Details of the deal have not been made public. The U.S. said it was signed electronically on Sunday but that it will not be implemented until a formal signing. Pakistan’s prime minister said that will happen Friday in Geneva.
