US will pressure Gaddafi until he leaves, Rice says

WASHINGTON - US Ambassador to the United Nations Susan Rice said on Tuesday that the United States will maintain political and economic pressure on Muammar Gaddafi until he steps down as Libyan leader.
Speaking in an interview on ABC's "Good Morning America" program, Rice also said it was premature to talk about providing material support to Libyan rebels who are fighting to oust Gaddafi, saying no clear-cut unified opposition has yet to coalesce.
