As the United States continues a significant military buildup in the Middle East, Iran has taken steps to signal its readiness for war, including fortifying its nuclear sites and rebuilding missile production facilities.

Tensions between the United States and Iran have caused an increase in oil prices across the country and here in New Jersey, according to experts.

DUBAI, Feb 22 (Reuters) - Iran and the U.S. have differing views over the scope and mechanism to lift sanctions on Tehran in exchange for curbs on its nuclear programme, a senior Iranian official told Reuters on Sunday,

President Trump is pressuring Iran to either curtail its nuclear program or face military strikes, after Iran amassed a large stockpile of highly enriched uranium. Here's what to know.

The gambit was successful. At least twice, the president weighed ordering an attack on Iran, only to be dissuaded by aides from moving forward. But America now appears to be on the brink of war with Iran again. And this time, instead of acting as a deterrent, the Pentagon’s war plans are being used to draw up options for the president to consider.

Within days of the U.S. strikes on Iran’s nuclear facilities last year, all sides agreed to a cease-fire. This time could be different.

President Trump has one bright red line for Iran's nuclear program and some areas of flexibility as he weighs military strikes or a possible deal in the coming days.

Defense expert Cameron Chell called Iran's military moves a "calculated escalation" as U.S. MQ-9 Reaper drones with strike capabilities were reportedly spotted in the region.
