President Donald Trump met with top advisers behind closed doors at the White House on Friday to discuss his options on Iran, including the possibility of significantly expanding military action against the country, according to two sources familiar with the matter.

The New York Times first reported on the meeting. Trump has held a number of similar strategy sessions with his national security team in the days since the ceasefire broke down.

Trump did not publicly indicate whether he had made up his mind on what course to take when he fielded questions from reporters Friday afternoon.

"As you know, we're locked and loaded. We're locked and loaded and ready to go, but we're talking to them," Trump said during an event in the Oval Office.

U.S. military forces disabled a ship on Friday that was attempting to break the blockade, according to a U.S. official.

This is now the fifth ship that has been disabled by U.S. military forces since the blockade against ships leaving or going to Iranian ships was reimposed on July 14.

The U.S. struck a security building near the Iraq-Iran border crossing at Shalamche that was determined to be a "legitimate military target," according to an official.

The U.S. official who said that an initial look video showing explosions near the Iraq-Iran border said it was not from a U.S. airstrike, now says there was a U.S. airstrike near the border crossing.

The building targeted was located on the Iranian side of the border, about 8 meters from the border with Iraq, according to the official
