US being 'humiliated' by Iran, German chancellor says
Rubio said Iran would not be allowed to charge Strait of Hormuz tolls.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Following the announcement of a two-week ceasefire, initial U.S.-Iran talks in Pakistan earlier this month failed to reach a peace deal.
Trump later announced the open-ended extension of the ceasefire and the continuation of the blockade until Iran's proposal is submitted and discussions are concluded "one way or the other."

Video shows gunmen seizing commercial ships, Iran 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.
Senate fails to advance Iran war powers resolution for 5th time
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.

Trump has 'not set a deadline' for Iran talks, proposal, White House says
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.
CENTOM says 29 vessels turned back, denies ships have evaded blockade

That ship is included among the 29 turned around ships.
