Four men, including two brothers, have been sentenced to prison in Sweden for their involvement with the terrorist organization IS in Somalia.

The convictions follow a high-profile raid in Tyresö last year by Swedish Security Police.

The men, aged between 20 and 63, received sentences ranging from three to six and a half years.

They were found guilty of recruiting for IS, spreading propaganda, and handling weapons.

However, they were acquitted of planning specific terrorist attacks due to insufficient evidence of a concrete plan.

The case has drawn attention to the use of secret surveillance, which played a key role in securing the convictions.

All four men deny the charges.
