Vandals defaced a Sikh house of worship in Riverside, California this week, spray painting the word “terrorist” around the complex. The incident comes as US Sikhs are marking the one-year anniversary of the mass shooting at a temple in Oak Creek, Wisconsin, where six worshippers were killed. Special days of prayer and community service are planned in remembrance.

There was also vandalism at Washington’s National Cathedral, where green paint was thrown in the historic Bethlehem Chapel and the Children’s Chapel. Cathedral officials say cleanup and restoration will cost $15,000. Green paint was also splattered on a statue of Martin Luther at a downtown Lutheran Church, the Lincoln Memorial, and other DC sites.
