WASHINGTON - US President Barack Obama said on Friday the United States and its allies are slowly "tightening the noose" on Libyan leader Muammar Gaddafi and that a no-fly zone remains an option to put pressure on him.
Obama, accused by critics of reacting too slowly to turmoil in Libya, told a news conference he believes international sanctions, an arms embargo and other measures are having an impact and that all other options remain on the table.
"Across the board we are slowly tightening the noose on Gaddafi. He is more and more isolated internationally," Obama said. "I have not taken any options off the table."
