Two Pakistani-born brothers are scheduled to plead guilty in Florida federal court to charges they plotted a terrorist attack against New York landmarks.

U.S. District Judge Beth Bloom scheduled a Thursday morning change-of-plea hearing for 32-year-old Sheheryar Alam Qazi and 22-year-old Raees Alam Qazi. The men previously pleaded not guilty to several terrorism-related charges, including conspiracy to provide material support.

The brothers also are charged with assaulting two U.S. marshals while being escorted in the Miami court complex.

The alleged plot never got beyond planning stages. The FBI says Raees Qazi traveled to the city in 2012 to scout targets but did not attempt any attacks. He was arrested after returning to Broward County, Florida, where the brothers lived.

Key evidence includes FBI wiretap and other communications intercepts.
