Tensions were already running high between Tehran and Washington in the wake of Iran's move to test-fire a next generation surface-to-surface ballistic missile with the range to hit Israel.
And then the IRGC conducted a live-fire rocket test within 1,500 yards of a US aircraft carrier in the Strait of Hormuz.
Now, in a further escalation, Iran has reportedly seized two US Navy ships.

- RHODES SAYS U.S. WORKING ON RETURN OF CREW
- RHODES SAYS U.S. WORKING TO RESOLV
But nobody panic, because Iran has promised to return the crew "promptly."
AP writes that the Pentagon says it briefly lost contact with two small Navy craft in the Persian Gulf on Tuesday but has received assurances from Iran that the crew and vessels will be returned safely and promptly.
Pentagon spokesman Peter Cook tells The Associated Press that the boats were moving between Kuwait and Bahrain when the US lost contact with them.
Cook says, "We have been in contact with Iran and have received assurances that the crew and the vessels will be returned promptly."
The crews, which total 10 Navy sailors, are being held at Farsi Island, a highly restricted island between Bahrain and Kuwait, where Iran has a naval base. US officials are saying it is unclear how the crew members ended up in Iranian waters, though Secretary of State John Kerry has kept phone contact with Iranian officials in Tehran, urging for a release. A senior official told NBC News the Iranians understand a mistake was made and have agreed to a release to come in hours.
According to AP, an anonymous senior official says Kerry "personally engaged with” Iranian Foreign Minister Javad Zarif to work out a solution almost immediately upon hearing of the development around 12:30 pm EST.
Josh Earnest, the White House spokesperson, said the sailors will be released "promptly" and " allowed to continue their journey."
