The Pentagon announced on Friday a new package of $150 million in military assistance for Ukraine that will include counter-artillery radar, electronic warfare equipment and counter-drone technology, bolstering Kyiv amid elevated tensions with Moscow.

Although the funds were already committed by Congress, the Defense Department's announcement details specifically how the U.S. military will allocate assistance earmarked for Ukraine before the end of the U.S. government's fiscal year in September.

The latest tranche of assistance will come in addition to the $125 million that the Pentagon announced on March 1, which included armed Mark VI patrol boats.

Moscow annexed Ukraine's Crimea region in 2014 and backed a pro-Russian separatist uprising in eastern Ukraine that triggered a conflict that has killed over 14,000 people.
