U.S. Secretary of State Hillary Rodham Clinton says the U.S. is sending assistance teams to Libya's borders with Egypt and Tunisia. The teams will help desperate refugees trying to flee a potential civil war.

Clinton says the U.S. has pledged $10 million to help refugees.

Speaking after a day of discussions with European allies in Switzerland, Clinton says the U.S. is leaving all its options on the table to deal with Libya.

She would not discuss military options in detail. But she says that so long as Libyan leader Moammar Gadhafi attacks his people the U.S. will consider a range of responses.
