LONDON (AP) — Britain’s foreign secretary says the government is aware of some Britons going to Syria to fight against President Bashar Assad’s rule, after police arrested two people on suspicion of traveling to that country to support terrorist activity.

William Hague told BBC radio Wednesday that the government is concerned. “That’s not something we recommend, and we do not want British people taking part in violent situations anywhere in the world.”

Police arrested a man and a woman, both aged 26, at Heathrow Airport late Tuesday, after they flew into the airport from Egypt.

Police did not make clear whether the suspects were thought to be returning from or heading to Syria. The statement said that officers were searching two homes in east London as part of the investigation.
