On December 10, 2001, The San Francisco Chronicle reported "Rocks shatter mosque's peace." It noted, "Rock-throwing vandals smashed the front window of an East Bay mosque early yesterday while 15 worshipers were inside celebrating a notably prayerful time in the Islamic fasting month of Ramadan. Two large river rocks, each twice the size of a fist, crashed through the 10-foot-by-5-foot window at The Islamic Center of Contra Costa on Clayton Road in Concord, showering the interior with broken glass." The article explained that "members of the mosque deplore terrorism" and noted that American flags were proudly displayed on the mosque's window.
