US being 'humiliated' by Iran, German chancellor says

Dramatic video broadcast on Iranian state TV purportedly shows Iranian forces seizing two commercial ships.

In the footage, speed boats are seen racing toward the massive vessels, MSC Francesca and the Epaminondas, which the Islamic Revolutionary Guard Corps Navy accused of "attempting to secretly exit the Strait of Hormuz."

Masked soldiers are seen climbing up to the deck of one of the ships while brandishing long guns.

Both vessels were transferred to Iranian territorial waters "in order to examine the cargo and documents," the IRGC Navy said.

ABC News verified with satellite imagery that the two vessels were near one another early Wednesday morning off the coast of Iran.

The Senate rejected an Iran war powers resolution for the fifth time on Wednesday.

The resolution, which needed 51 votes to advance, failed by a vote of 46-51. As with previous votes, Sen. Rand Paul was the lone Republican to vote for the resolution and Sen. John Fetterman was the only Democrat to vote against it.

Democrats have vowed to continually bring up war power resolutions that direct the "removal of United States Armed Forces from hostilities within or against the Islamic Republic of Iran that have not been authorized by Congress" as long as the conflict continues.

White House press secretary Karoline Leavitt said there is no set deadline for the ceasefire with Iran that was extended by President Donald Trump on Tuesday and that any reports that Trump had set a three to five day timeline for a unified peace proposal from Iran are "not true."

"I'm not going to set a timetable for the president. He has not done that, and I won't. I know there's been some anonymous, sourced reporting that there was maybe a three to five day deadline. That is not true. The president has not set a deadline himself," Leavitt told reporters at the White House on Wednesday.

Leavitt placed blame on Iran over the fact that a peace deal has not been finalized but also suggested that Trump has given Iranian leaders flexibility on coming up with a proposal.

"The president chose to extend the ceasefire because it's Iran who needs to get their acts together," she said.

U.S. Central Command said 29 ships have been turned back or returned to Iranian ports as part of the U.S. blockade.

CENTCOM also pushed back on reports that other ships were able to evade the blockade and called those reports inaccurate. But, acknowledge that one ship, the Dorena, is currently under escort by a U.S. Navy destroyer in the Indian Ocean "after previously attempting to violate the blockade."

That ship is included among the 29 turned around ships.
