Via the Washington Post, Libya has declared a “cease fire” and “immediate stop to all military operations” in response to the passage of the U.N. Security Council resolution last night:

“We decided on an immediate cease-fire and on an immediate stop to all military operations,” Libyan foreign Minister Musa Kusa told reporters in the capital. He said Libya “takes great interest in protecting all civilians and protecting human rights,” adding that the government would also protect foreigners and foreign assets in the country.
Libya “accepts that it is obliged to accept the U.N. resolution,” Kusa said in explaining the decision to declare a cease-fire.
He said the cease-fire “will take the country back to safety” and ensure the security of all Libyans. But he also criticized the U.N. Security Council’s authorization of military action, which he said violates Libya’s sovereignty.
