WASHINGTON (AP) — Vice President Joe Biden has called Ukraine's president to express "grave concern" about violent clashes in the capital of Kiev.
The White House says Biden called on President Viktor Yanukovych (yah-noo-KOH'-vich) Tuesday to pull back government forces and exercise maximum restraint. Riot police armed with stun guns and water cannons attacked a protest camp in Kiev Tuesday, killing at least 18 people and injuring hundreds.
The White House says Biden made clear that while the United States condemns violence by all parties, the government bears "special responsibility to de-escalate the situation." Biden also called on Ukraine's government to address the protestors' "legitimate grievances" and put forward proposals for political reform.
Biden has spoken frequently with Yanukovych during the standoff between the government and protesters.
