fighting against al-qaeda, and when the americans were giving him money and other kinds of support to do that. in 2006, for instance, they were able to dig a tunnel 140 meters from the central jail in sanaa and safely leave the city. after that they escalateed their attacks on the targets in yemen. now it is a very favorable situation for houthies and saleh to see al-qaeda coming back, because that proves a point. ali abdullahali abdullah saleh said that he has been able it to keep al-qaeda in check. and now ali abdullah saleh al-qaeda will reappear. we've seen a jail break a year ago, and then the phenomenon of isis in iraq when several people
