British Foreign Secretary William Hague said Monday that the Syrian regime could face more sanctions as he reiterated his call for President Bashar al-Assad to implement reforms or leave power. \"The situation remains very serious and, if anything, is deteriorating,\" Hague told reporters as he arrived for a meeting of European Union foreign ministers in Brussels. \"It is really up to the Syrian people but I believe he should reform or step aside,\" he said. The European Union has slapped asset freezes and travel bans on the Damascus regime, including against Assad, in response to a brutal crackdown on anti-government protests. \"Certainly there will be a time for further sanctions,\" Hague said.
