The US ambassador in charge of counterterrorism said Saturday that parts of Pakistan are a "safe haven" for militants and that Osama bin Laden was more likely to be hiding there than in Afghanistan. Henry Crumpton lauded Pakistan for arresting "hundreds and hundreds" of al-Qaida figures but said that it needed to do more. "Has Pakistan done enough? I think the answer is no. I have conveyed that to them, other US officials have convyed that to them," he told reporters at the US Embassy in Kabul after talks with Afghan officials. "If we knew exactly where bin Laden was, we'd go get him," Crumpton said. "But we're very confident he's along the Pakistan-Afghan border somewhere," he said. He added that there was a "higher probability" bin Laden was hiding on the Pakistan side.
