Pentagon to send $150M military assistance package to Ukraine

Flashback: In 2014, the Russian government invaded and seized Ukraine's Crimea region, backing a pro-Russian separatist rebellion in eastern Ukraine that killed over 14,000 people.

• In recent months, Ukraine and Russia have taken shots at each other amid a surge in fighting in Ukraine's Donbas. In what it called a defensive operation, Russia amassed troops on its border with Ukraine and in Crimea, per Reuters.

Details: The new funds, which were already committed by Congress, join $125 million already set aside for Ukraine.

• The Pentagon said the assistance includes capabilities "to enhance the lethality, command and control and situational awareness of Ukraine's forces," according to Reuters.
• The United States will also provide training and equipment to bolster Ukrainian Air Force bases.

The big picture: Biden reassured Ukrainian President Volodymyr Zelensky on Monday that he will stand up for Ukraine's sovereignty.

• A Ukraine defense memo leaked in April revealed that Russia has been holding last-minute military exercises near commercial shipping lanes in the Black Sea that threaten to strangle Ukraine's economy, Axios' Jonathan Swan and Zachary Basu report.
