Updated: there has been an arrest.
George Tiller, a Wichita doctor who was one of the few doctors in the nation to perform late-term abortions, was shot to death on Sunday as he attended church, city officials in Wichita said.
Dr. Tiller, who had performed abortions since the 1970s, had long been a lightning rod for controversy over the issue of abortion, particularly in Kansas, where abortion opponents regularly protested outside his clinic and sometimes his home and church. In 1993, he was shot in both arms by an abortion opponent but recovered.
Andrew Sullivan notes that Tiller was a frequent target of Bill O'Reilly.
