A Swedish prosecutor has decided not to press charges against the three Swedes arrested on suspicion of funding terrorism earlier this year.
Prosecutor Ronnie Jacobsson said Friday he could not prove that the men had intended to send money to terrorist organizations.
The three - all Swedish citizens in their 30's and 40's - were arrested in raids in Stockholm in February. They were are accused of using the informal money transfer networks called hawalas to send funds to alleged terror groups in Somalia.
The paperless system, based on trust and oral agreements, is commonly used in the Middle East, parts of Asia and Africa.
Two of the men were held for more than three months before being released at the start of the summer.
