The U.N. Security Council is set for a second day of emergency talks on Libya -- with members considering possible sanctions against Moammar Gadhafi's government over its violent crackdown on protesters.
United Nations Secretary-General Ban Ki-moon Friday urged the Council to take what he called "concrete action" to protect the anti-government protesters.
He asked members to move quickly on a resolution drafted by Britain and France that calls for an arms embargo, along with asset freezes and travel bans on specific individuals in Libya.
The European Union Friday agreed to impose an arms embargo on Libya, along with a travel ban and assets freeze. And U.S. President Barack Obama signed an executive order imposing unilateral sanctions on the nation.
The U.N. High Commissioner for Human Rights, Navi Pillay, says there are reports of mass killings in Libya that should spur the international community to step in to end the violence. She called for an independent investigation of the reports that thousands of Libyans have been killed or wounded by Libyan security forces.
