The White House said on Sunday it would continue to arm Ukraine but declined direct comment on an explosion that damaged Russia's road-and-rail bridge to Crimea.
"We don't really have anything more to add to the reports about the explosion on the bridge," White House national security spokesman John Kirby told ABC's "This Week" program. "What I can tell you is that Mr. Putin started this war, and Mr. Putin could end it today, simply by moving his troops out of the country."
