An Islamic center east of San Francisco was attacked early Saturday with a Molotov cocktail, KCRA reported. “It’s very clear to me it’s a hate crime,” said Ghaleb Abdulla, a member of the board of trustees at the mosque in Tracy, California. Officials at the site said no one was injured or inside when the firebomb hit the building. Congregants gathered Sunday and prayed that sheriff’s officials will find the attackers. Suspects used a wine bottle containing a rag and accelerant that exploded when it hit the building.
