Al Qaeda Leader Threatens 'Gravest Consequences' If Boston Marathon Bomber Executed, Reports Say
BOSTON (CBS) – The leader of Al Qaeda has reportedly warned the United States of the "gravest consequences" if Boston Marathon bomber Dzhokhar Tsarnaev is executed.
According to multiple reports, Ayman al-Zawahri released a new video Friday making the threat.
Tsarnaev is specifically named in the video in which al-Zawahri threatens the U.S. if Tsarnaev or any other Muslim prisoners are executed, according to Reuters.
The FBI's Boston office declined comment to WBZ-TV when asked about the video.
Tsarnaev apologized for the attacks moments before he was sentenced to death in June 2015.
He is currently being held at the high-security Supermax federal prison in Florence, Colorado while he appeals the death sentence.
Tsarnaev, 22, was convicted of federal charges in the April 2013 bombings on Boylston Street. Three people were killed and more than 260 others were wounded.
