LONDON - Police investigating the death of a British teenager who was killed fighting in Syria last month raided his family's home on Tuesday with warrants issued under anti-terrorism legislation.

Abdullah Deghayes, 18, died after traveling to Syria with his two brothers to fight alongside rebel forces against President Bashar Assad.

Police and counter-terrorism forces said they were searching four houses in southeast England as part of an investigation into the teenager's death.

They said the raids, which began early on Tuesday morning, were not in response to any immediate threat and that no arrests were expected.

Abdullah Deghayes' father, Abu Bakr Deghayes, said he was being held with his family in a small room inside his Brighton house.

"It's very upsetting and frustrating. If there was another way to deal with this I would have happily complied. I just can't understand why they would put my family through this," he said, speaking by phone to the support charity CAGE.
