Washington: President Donald Trump said Thursday that Iran has made a "very big mistake" by shooting down a US spy drone, an incident that is likely to further escalate already soaring tensions between Washington and Tehran. Both the US and Iran said that Iranian forces had shot down an American military surveillance drone, but the two sides offered conflicting details on the incident.

The BAMS-D drone was downed by an Iranian surface-to-air missile system while flying in international airspace over the Strait of Hormuz, a US Central Command spokesman, Navy Captain Bill Urban, said in a statement.
