Washington: US President Barack Obama on Wednesday said that the United States strongly condemns the use of violence on protesters in Libya and said a unified international response was forming.

"The suffering and bloodshed is outrageous and it is unacceptable," Obama said in his strongest and most direct statements to date on the unrest in Libya. "So are threats and orders to shoot peaceful protesters and further punish the people of Libya. These actions violate international norms and every standard of common decency. This violence must stop."
