Pakistan said Saturday it had some "good leads" in the effort to free a kidnapped American UN official after his captors set a 72-hour deadline to kill him if their demands were not met. Interior ministry chief Rehman Malik travelled to Quetta to oversee efforts to secure the release of John Solecki, who was kidnapped at gunpoint last week. "We have sufficient good leads which I cannot share right now. I hope to God and pray to God and inshallah we will succeed in recovering him," Malik told reporters after meeting top officials.
