WASHINGTON, May 5 (Reuters) - Ten civilian sailors have died due to the ongoing conflict in the Strait of Hormuz, U.S. Secretary of State Marco Rubio told reporters on Tuesday.

Speaking at the White House, Rubio said the U.S. would continue to deploy its assets to defend freedom of navigation in the key thoroughfare.

"They're isolated, they're starving, they're vulnerable and at least 10 sailors have died as a result, civilian sailors," Rubio said, without providing additional details.

Trump told reporters in the Oval Office that Iran's military has been reduced to firing "peashooters" and that Tehran privately wants to make a deal despite its public sabre-rattling.

"They play games, but let me just tell you, they want to make a deal. And who wouldn't, when your military is totally gone?" he said.
