i'm holly firfer. the u.s. embassy in yemen is cloessed today because of al qaeda threats against american interests. now the embassy is not saying if there's any specific threat, and it's unclear when it might reopen. the british embassy in the yemeni capital is closed today. yemen is pledging more cooperation in the fight against terrorism. and experts on the region warn it will take a lot of time and resources to root out al qaeda in that country. >> the al qaeda threat is not simply to u.s. interests but very much to yemeni interests as well. the people of yemen have suffered a great deal, in terms of economic well-being because of al qaeda's activities there. so that's number one. and i think the second thing is that, based on that, actions by yemeni security forces are likely to be much more effective in countering the al qaeda threat in yemen than direct action by u.s. military forces. >> there are no easy, no obvious solutions in yemen. but one of the most important things for the u.s. to ceremony that
