President Barack Obama says the U.S. is providing Ukraine with $5 million worth of body armor, night-vision goggles and communication equipment as the country's battle against pro-Russia separatists continues.
Obama announced the aid after meeting with Petro Poroshenko, the country's future president, while both were visiting Warsaw, Poland, on Wednesday.
Poroshenko will be sworn into office this weekend.
The White House says Obama has approved more than $23 million in security assistance to Ukraine since early March, when the situation began to deteriorate.
The United States already has provided ready-to-eat meals and money for medical supplies and other non-lethal assistance, including clothing, sleeping bags and generators.
The U.S. has supported Ukraine's right to self-determination following Russia's annexation of Crimea earlier this year.
