2 British men get nearly 13 years in prison for terrorism offenses after returning from Syria

Two British men who travelled to Syria to join an al-Qaida linked terrorist group have received lengthy prison sentences.

Longtime friends Mohammed Ahmed and Yusuf Sarwar from the central English city of Birmingham received sentences of nearly 13 years each Friday.

The 22-year-olds had pleaded guilty to one count of preparing terrorist acts. They had been arrested at London's Heathrow Airport while trying to return from Syria.

Judge Michael Topolski said the two "enthusiastically" tried to commit acts of terrorism and were deeply committed to violence.

British officials have warned of an increase in recent months of the number of Britons joining extremist groups in Syria. They warn that some are planning to bring terrorist tactics back to Britain.
