Stockholm - A Swedish prosecutor Friday dropped charges against three men arrested in February on suspicion of funding terrorism in Somalia.

Prosecutor Ronnie Jacobsson told Swedish radio news that he had not been able to prove the suspicions against the three men.

Two of the men were released in June but were ordered to report regularly to the police. A third man was released already in February.

The men were Swedish nationals of Somali origin, and according to Swedish security police channelled funds to the militant Islamist group al-Shabab.

The group has been part of the insurgency against Ethiopian-backed forces in Somalia.

Security police in neighbouring Norway also conducted raids on the same day in February and detained three men of Somali origin, one was held in custody. (dpa)
