President Donald Trump said the U.S. played no role in the explosion of an Iranian missile on its launchpad Thursday, tweeting what appeared to be a photograph of the site with labels describing the damage.

The explosion came just days after Trump said he’d be willing to meet Iranian President Hassan Rouhani under the “correct” circumstances, and following French President Emmanuel Macron’s decision to invite Iran’s foreign minister, Javad Zarif, to join other leaders on the sidelines of the Group of Seven summit in Biarritz last weekend.

Tensions between the U.S. and Iran have escalated since the Trump abandoned the 2015 multilateral deal to stem the Islamic Republic’s nuclear program.

Trump told reporters at the White House on Friday evening that he had the authority to release the photo. “We had a photo and I released it, which I have the absolute right to do,” Trump said.

He also reiterated that the U.S. wasn’t involved in the explosion. “They were going to set off a big missile and it didn’t work out too well,” he said. “Had nothing to do with us.”
