Trump tweets 'Iran made a very big mistake!' after alleged shoot down of spy drone

Washington: President Donald Trump said Thursday that Tehran had made a "very big" error, after Iran shot down a US spy drone near the strategic Strait of Hormuz.

"Iran made a very big mistake!" he tweeted.

Iran's Islamic Revolutionary Guard Corps earlier said it had brought down the surveillance drone after it entered its country's airspace. The Pentagon said the incident occurred in international airspace.

Oil prices jumped Thursday by 6 per cent on rising US-Iran tensions, with gains accelerating after the cryptic tweet.
