Syrian President Bashar al-Assad has said that he US-led coalition against ISIS in Syria is “illusive,” noting that the terrorist group was expanding during US operation.

Assad also questioned new US President Donald Trump’s pledge to fight ISIS terrorists, SANA reported on Tuesday.

“What we heard as statements by Trump during the campaign and after the campaign is promising regarding the priority of fighting terrorists, and mainly ISIS, that’s what we’ve been asking for during the last six years,” he said.

He also said that it is still too early to expect anything practical.

“It could be about the cooperation between the US and Russia, that we think is going to be positive for the rest of the world, including Syria. So, as I said, it’s still early to judge,” the Syrian president said.

He further said the US operations inside the Arab country were illegal because they were carried out without consulting with the Syrian government.

“Let me be frank with you, when you talk about contribution in the operation against ISIS, actually there was no operation against ISIS; it was a cosmetic operation if you want to talk about the American alliance against ISIS.”

Assad also said the US operation in Syria is a breach of the country’s sovereignty.
