JAKARTA, Jan. 15 (UPI) -- Indonesian police arrested three suspects allegedly linked to a bomb and gun attack that killed seven people in the nation's capital of Jakarta.
All three suspects are Indonesian and were arrested in their homes in a pre-dawn commando raid Friday in the town of Depok, about an hour-and-a-half from Jakarta.
The three allegedly have connections to the Islamic State and were part of a militant group led by Indonesian Bahrun Naim, currently believed to be fighting in Syria and whom police believe planned the attack.
Police also said the five attackers killed in the siege were linked to the IS -- also identified as Daesh, ISIS and ISIL -- and two might have been previously convicted of terrorism.
IS has claimed credit for the attacks that also injured 26 people, saying it targeted non-Indonesians -- especially those from Western countries fighting the terrorist group in Iraq and Syria.
Security has been ramped up at airports and public places visited by foreigners.
