Mosque says bombing suspects were 'occasional visitors,' never violent

A mosque outside Boston said Saturday that the two brothers suspected in the bombing of the Boston Marathon were “occasional visitors” who never “exhibited any violent sentiments or behavior.”

The Islamic Society of Boston Cambridge Masjid said in a statement that its community was “in shock to have learned of the crimes of these individuals.”

People who knew Dzhokhar and Tamerlan Tsarnaev, the men authorities say set off twin blasts near the marathon finish line Monday, have been urged to call law enforcement and have done so, the mosque said.

Dzhokhar Tsarnaev was captured alive hiding in a boat outside a home in Watertown, Mass., and was in serious condition Saturday and under heavy guard at a Boston hospital. Authorities were waiting to question him and were preparing charges.

Tsarnaev was injured in a firefight with Watertown police early Friday that left his brother dead.

Federal authorities are trying to determine a motive for the attack, which killed three people and injured 176.

The FBI confirmed that it questioned Tamerlan Tsarnaev in 2011 for possible extremist ties after a tip from a foreign country that he was a “follower of radical Islam” and planned to join an underground group.

Agents talked to him and neighbors and did not find “any terrorism activity, domestic or foreign.”

The Islamic Society of Boston Cultural Center, the largest Islamic place of worship in New England, closed for the day Friday after The Boston Globe reported that one of the suspects had worshipped there.
