US Ambassador to Iraq Ryan Crocker told The Associated Press Friday that suicide bombings by two women in Baghdad show that a resilient al-Qaida has "found a different, deadly way" to try to destabilize Iraq. "There is nothing they won't do if they think it will work in creating carnage and the political fallout that comes from that," he said in an interview at the State Department. "We and the Iraqis are going to have to stay on this. "They have found a different, deadly way to do this," Crocker said. "Al-Qaida has been damaged, but ... it is still there, it is resilient and it is determined." "Their car bomb capabilites have been badly disrupted so now, as we saw today and as we've seen for some time, they are moving toward suicide vests, in this case suicide vests worn by women," he said. "No one's doing victory dances and today's horrific bombings illustrate why that's the case."
