DUBAI - Iran's Supreme Leader Ayatollah Ali Khamenei told Iranian officials on Wednesday to stop bickering over mounting economic woes as Tehran grapples with Western-imposed sanctions, voicing concern heightened by the collapse of the rial currency.

His comments touched on divisions between Iranian government agencies and political factions exacerbated by the rial's fall over the past several weeks, fanning an atmosphere of crisis in the world's No. 5 oil-exporting state.

"The country's officials should know and accept their responsibilities and not blame each other," Khamenei said in a televised speech in the northeastern city of Bojnourd. "They should be united and sympathize with each other."
