Trump says intelligence on Iran was inconclusive, but suggests severe damage

US President Donald Trump said on Wednesday that the intelligence following the strikes on Iranian nuclear sites was inconclusive, but also suggested the damage could have been severe.

"The intelligence was very inconclusive. The intelligence says we don't know. It could've been very severe. That's what the intelligence suggests," Trump told reporters ahead of meeting with world leaders at a Nato summit.

"It was very severe. There was obliteration," he added.
