Republican presidential candidate Donald Trump said Tuesday that the U.S. would have "absolutely no choice" but to close down some mosques in the wake of last week's terror attacks in Paris that killed 129 people and injured 350 others.

"Nobody wants to shut down religion institutions or anything, but you understand it." Trump told Fox News' Sean Hannity. "A lot of people understand it. We’re going to have no choice."

"Some really bad things are happening and they’re happening fast."

Trump also repeated his vow to "blast the hell out of ISIS" in the wake of Friday's attacks, the deadliest to befall a Western European capital since 2004.

"I’d get everybody together—this includes Russia—and I’ve been right about that too."Trump said. Now, all of a sudden Putin’s going wild with bombing ISIS, and that’s a good thing, not a bad thing. Who needs to take the credit? Let him have some credit."

The real estate mogual reaffirmed his stance against allowing Syrian refugees into the country in the wake of reports that at least one of the attackers made his way to France via Greece and refugee camps in the Balkans.

"You look at what’s happening in terms of this migration and in terms of what’s coming, we have no idea – will they assimilate?" Trump said. "Are they gonna be able to assimilate? I don’t know that they even want to assimilate, and yet, we take everybody."

Earlier Tuesday, Trump accused the Obama administration of sending refugees primarily to Republican-led states.

The U.S. has admitted roughly 2,500 Syrians since the civil war erupted in that country in the spring of 2011, State Department officials said. Of that number, about half are children. About 2 percent are single men of combat age. The overall pool is almost evenly split between males and females.
