The US, Europe and Arab nations Thursday crafted a stern warning to Syrian President Bashar Assad: Agree to an immediate cease-fire and allow humanitarian aid into areas hardest hit by his regime's brutal crackdown on opponents, or face as-yet unspecified punishments.
US, European and Arab officials met in London to work out details of an ultimatum to Assad. Diplomats said it would demand immediate compliance or result in additional punitive measures, likely to include toughened sanctions. The ultimatum is to be presented at a major international conference on Syria set for Friday in Tunisia. (AP)
