The Iranian government refused a formal request by the U.S. on Tuesday to return an unmanned surveillance drone that was captured by Iran's military earlier this month. Instead, Iranian officials insisted the U.S. apologize for invading its airspace. Iranian television broadcast images of the RQ-170 Sentinel on Monday night, saying scientists were collecting data from the drone. U.S. officials say the drone malfunctioned, countering Iran's claim that electronic warfare brought down the drone. The U.S. says this is the latest provocation of the West by Iran, following an alleged plot to assassinate the Saudi ambassador to the U.S., and the storming of the British embassy in Tehran.
