DAVOS (Reuters) - Prime Minister David Cameron has dismissed any prospect of taking military action against Syrian President Bashar al-Assad's regime but vowed to "tighten the ratchet in all the ways we can."
Britain and France have joined efforts at the United Nations to end Assad's rule. Several diplomats said they were working with Qatar and other Arab delegations on a new draft resolution supporting an Arab League plan that envisages Assad stepping down and making way for a unity government to halt the bloodshed of a 10-month uprising.
