OXFORD, Miss. - A Mississippi woman who once sought to disguise a planned journey to join the Islamic State group as her honeymoon has been sentenced to 12 years in prison on a terrorism charge.

Vicksburg native Jaelyn Young was sentenced Thursday by U.S. District Judge Sharion Aycock. Young pleaded guilty in March to one count of conspiring to provide material support to a terrorist organization.

Young had faced up to 20 years in prison. Her parents pleaded for leniency Thursday, and Young broke down in heavy sobs at sentencing, saying she was ashamed of her actions.

Her fiance, Muhammad Dakhlalla, pleaded guilty March 11 to a similar charge and is set to be sentenced Aug. 24. Prosecutors have said Young, who converted to Islam while studying at Mississippi State University, had prodded Dakhlalla into the plan.

The two were arrested in 2015 before boarding a flight from Columbus, Mississippi.
