[h=1]Attacks against U.S. Muslims spike during Ramadan[/h] (CNN) – To mark the end of Islam's holiest month, Iftikhar Ali will head not to a mosque but to a convention center guarded by law enforcement officers. That's because this month, during Ramadan, the mosque in Joplin, Missouri, burned to the ground. Its rubble smoldered for two days as a shocked Muslim community came to terms with what had happened. ... Just Thursday, Ahmed Rehab, the head of the council in Chicago, received a call from a young man visiting his father's grave at Evergreen Cemetery. Someone had desecrated several Muslim graves. The Prophet Mohammed's name was taken in vain and, a black marker scrawl on a tombstone screamed: "raghead," a derogatory term for Muslims that stems from head coverings such as turbans and kaffiyas. A few days earlier, police arrested 51-year-old David Conrad and accused him of firing a pellet gun at a mosque filled with 500 people in Morton Grove, southern Chicago suburb. No one was injured but worshipers said one of the bullets flew only inches above a security guard's head, according to CNN affiliate station WGN. Conrad is a neighbor and had previously spoken out against the expansion of the mosque. He was charged with four felonies. In a third Chicago-area incident, worshipers at an Islamic school in Lombard heard a loud noise outside of the building during night prayers. They then found a 2-liter soda bottle filled with acid. Police identified it as a homemade bomb. ... In Murfreesboro, Tennessee, a new mosque opened earlier this month after more than two years of community protests, legal hurdles and vandalism. The board of directors planned for extra security. When worshipers bow their heads in prayer Sunday, someone else will be scanning the room. "Yes, we are very concerned because we have been the subject of vandalism, arson, bomb threats, intimidation, bullying," said Saleh Sbenaty, a board member of the Islamic Center of Murfreesboro. "You call it," he said. "Every single act of intimidation, you know, was actually inflicted upon us." ... ...Republican congressman Joe Walsh of Illinois, who warned Americans that "there is a radical strain of Islam in this country" and that radicals are "trying to kill Americans every week." Justin Roth, Walsh's chief of staff, said that the lawmaker's comments were taken out of context and that Walsh is troubled by attacks on any people based on their religion. ... There were other troubling incidents this month: – In Hayward, California, police arrested two teens and charged them with committing a hate crime after worshipers said the boys threw lemons at them during prayer. – In Ontario, California, pig legs were left on the property of an Islamic Center. Police still do not have information on who was responsible for the act, which was particularly offensive during Ramadan because practicing Muslims consider pigs unclean. – In North Smithfield, Rhode Island, a surveillance camera outside the Masjid Al-Islam mosque showed a suspect breaking the building's sign and two vehicles later fleeing the property. – In Oklahoma City, vandals defaced the Grand Mosque with paintball guns. Those inside feared the shots came from a real gun. In Joplin, the torched mosque's 90 congregants invited 300 other people to join them Sunday for Eid.
