Brothers Mohommod Hassin Nawaz, 31, Hamza Nawaz, 23, became the first Britons Wednesday to be convicted for attending a military training camp in Syria.
The brothers were found guilty of conspiracy to attend a terrorist training camp, and the judge at London's Old Bailey sentenced Mohommod and Hamza to four and three and a half years in prison, respectively.
The brothers were arrested in September 2013 after rifle ammunition, cash, and a balaclava were found in their car at the southeastern port of Dover.
Police also found communication on their phones indicating they had attended a camp in the Latakia province of Syria.
