BOSTON — A fugitive with ties to Massachusetts has been added to the FBI’s list of most-wanted terrorists, the agency announced Wednesday.

Ahmad Abousamra was indicted in 2009 after federal prosecutors said he took multiple trips to Pakistan and Yemen, trying to get military training for the purpose of attacking U.S. soldiers overseas.

The FBI says Abousamra, who once lived in Mansfield, was an associate of Tarek Mehanna, a Sudbury man who was convicted in 2011 on four terrorism charges and later sentenced to 17 1/2 years in federal prison.

In October 2012, the FBI offered a $50,000 reward for information leading to the capture and return of Abousamra, who authorities believe may be living in Aleppo, Syria, with his wife and other family members. He is said to be of Syrian descent with dual citizenship in the U.S. and Syria.

Vincent Lisi, special agent in charge of the FBI’s Boston office, said Wednesday that the reward remains in place and that Abousamra’s name has been added to the Most Wanted Terrorists List, which was created after the Sept. 11, 2001, terrorist attacks. There are now 30 names on the list.

“In this case, Ahmad Abousamra advocates violent extremism and boldly promotes violence against United States citizens and military personnel,” Lisi said in a statement.

The FBI hopes that the international exposure from the list will help authorities track down the suspect, Lisi said.

Prosecutors said during Mehanna’s trial that Mehanna and Abousamra had failed to find a terrorist training camp.

The indictment against Abousamra charged him with conspiracy to provide material support to terrorists, providing and attempting to provide material support to terrorists, conspiracy to kill in a foreign country, conspiracy and false statements.
