Iran’s foreign minister says the US should set aside its extravagant demands and take realistic steps toward reaching an agreement to revive the 2015 Iran deal.

For the first time since the Krelim launched a military operation in Ukraine nearly three months ago; US defense secretary Lloyd Austin and his Russian counterpart Sergei Shoigu spoke over the phone on Friday.

The mysterious new Phoenix Ghost UAV – also dubbed as “suicide drone” -- the US supplies to Ukraine was a project overseen by a secretive Air Force office known as Big Safari, the Pentagon has revealed.

The Pentagon says that the “Ghost” drones the US will send to Ukraine are designed for attacking targets and are destroyed after a single use.

The Russian government has slapped a new round of entry ban on top US and Canadian officials and individuals.

The US government is struggling to track large quantities of “lethal aid” shipped to Ukraine in recent months amid raging conflict in the country, according to a stunning new revelation.

The US military will ship an additional $300 million in war-fighting equipment to Ukraine that includes laser-guided missiles and drones.

The Pentagon says US troops in Poland are "liaising" with Ukrainian forces as they hand over weapons to them, but are not training "in the classic sense."

Pentagon press secretary John Kirby says that time is "shrinking" when it comes to finding a diplomatic resolution to the alleged Russian military buildup at the Ukrainian border.

There are growing calls for accountability a day after the US announced it will not hold any of its military personnel accountable for a deadly August drone strike that killed 10 civilians, including seven children, in Afghanistan.
