(Reuters) - The suspect in a mass shooting at a synagogue in Pittsburgh that killed 11 worshipers has been charged on a total of 44 counts, up from 29 counts previously, according to a federal indictment filed on Wednesday.

The charges against Robert Bowers, the suspect in what is believed to be the deadliest attack on Jews in the United States in recent history, include religious hate crimes, firearms charges and causing injury to police officers. Bowers is due to appear at a second hearing in federal court in Pittsburgh on Thursday.
