The FBI on Sunday identified British national Malik Faisal Akram, 44, as the person who took hostages in a standoff at a Texas synagogue, apparently acting alone. None of the four hostages at Congregation Beth Israel in Colleyville, a city of 26,000 people 15 miles northeast of Fort Worth, were injured. The hostages included Rabbi Charlie Cytron-Walker, who said Sunday that the assailant was “increasingly belligerent and threatening” in the standoff’s last hour. A law enforcement official who spoke to USA TODAY on the condition of anonymity said Akram demanded the release of Aafia Siddiqui, a Pakistani neuroscientist serving 86 years in a Texas prison for attempting to kill Americans in Afghanistan. Siddiqui is suspected of having ties to al-Qaida. Marwa Elbially, Siddiqui’s Texas-based lawyer, told USA TODAY that Siddiqui was not involved in the hostage situation and that her only brother, an architect who lives in Houston, confirmed that he had nothing to do with it, either. 📸: Smiley Pool/AP
