Group behind abduction of Linda Norgrove

Interesting Daily Telegraph article on Jamaat-ud-Dawa al-Quran wal'Sunnah and its leader Qari Ziaur Rahman, the group thought to have been responsible for kidnapping Linda Norgrove. Surprisingly little has been written about this organisation, considering its long history and significance in Kunar and Nuristan. Anyone got any more info? Qari Ziaur Rahman, who is also said to be the most senior Taliban leader in Kunar province - others say he works for al-Qaeda - was wrongly reported killed in US airstrikes both last year and again in March this year. The US is known to have posted a $350,000 reward some time ago for his death or capture, but he appears to have avoided both so far. An interview with him, conducted by Asia Times in 2008, can be found here.
