A Corvallis police vehicle sits in front of the Salman Al-Farisi Islamic Center following the fire set by an alleged arsonist in the early morning hours of Sunday, Nov. 28, 2010 in Corvallis, Ore.  Anger on Sunday over a Somali-born teen's failed plan to blow up a van full of explosives during Portland's Christmas tree lighting ceremony apparently erupted in arson on Sunday when a fire damaged the Islamic center once frequented by the suspect. Police don't know who started the blaze or exactly why, but they believe the mosque was targeted because terror suspect Mohamed Osman Mohamud, 19, occasionally worshipped there.
