Roshonara Choudhry, 21, was convicted of attempted murder Tuesday for stabbing Parliamentarian Stephen Timms at his surgical center in May, The Daily Telegraph reported.
Choudhry was radicalized by watching Internet videos of Anwar al-Awlaki, the American-born Yemen-based terrorist wanted over last week's attempt to blow up aircraft, the report said.
British officials said more than 5,000 postings featuring Awlaki's videos were available on YouTube Tuesday, and in one sermon he told followers "Jihad today is obligatory on every capable Muslim."
British officials called on the Obama administration to "take down this hateful material" in cases where servers were based in the United States, saying the Web sites "incite cold-blooded murder," and would "categorically not be allowed in the United Kingdom."
Police believe Choudhry was radicalized purely by Awlaki's online sermons, because she had no direct contact or other encouragement from extremists.
Awlaki's teachings also inspired the U.S. Army major accused of killing people at Fort Hood, Texas, last year. Awlaki was also linked to the Sept. 11, 2001, attacks and the attempted bombing of an airliner over Detroit last December.
Timms fully recovered from his injuries, the report said.
