The White House is urging Libya's neighbors to detain Moammar Gadhafi and members of his family if they seek refuge in another country.
White House spokesman Jay Carney says the U.S. has specifically delivered that message to Niger, which shares a porous desert border with Libya. Convoys of former regime loyalists, including Gadhafi's foreign minister, fled into Niger this week.
A United Nations resolution prohibits Gadhafi and his family, along with some other regime officials, from traveling outside of Libya. Carney said the U.N. must be notified immediately if anyone on the travel ban list has entered another country.
Algeria, another of Libya's neighbors, says several of Gadhafi's family members, including his wife, have crossed into the country.
