WASHINGTON, Rajab 2, 1436, Apr 21, 2015, SPA -- The United States will supply Ukraine with nearly $18 million in aid to provide shelter, food vouchers, potable water and health and sanitation in regions affected by fighting between government forces and pro-Russia fighters, according to AP. The White House says Vice President Joe Biden informed Ukrainian President Petro Poroshenko about the new assistance in a telephone call Monday. The two men are welcoming efforts by the Organization for Security and Cooperation Europe to seek a permanent ceasefire in areas still experiencing fighting. Both are calling on Russia to abide by earlier agreements and stop moving troops along the Russia-Ukraine border. The call came as U.S. and Ukraine troops kicked off joint training exercises intended to help bolster Ukraine's defenses against incursions from the Russian-backed separatists in the east. --SPA 03:24 LOCAL TIME 00:24 GMT www.spa.gov.sa/w
