Police in Indonesia have identified four out of five of the Jakarta attackers, the BBC reported on Friday.

Two of the attackers were previously convicted militants.

Police named one - Afif Sunakim, seen carrying a gun and rucksack during the attacks. He was jailed for seven years for attending a militant camp.

All five died in Thursday's attacks, which left two civilians dead and were claimed by Daesh terrorist group.

Three arrests were made on Friday but it is unclear if they are connected.

Security forces battled militants for hours in the busy commercial district where the militants struck.

A Canadian and an Indonesian national died, and at least 20 people were injured.

The assault ended when two attackers died in a suicide bombing, police say, with the other three killed in gun battles.

Jakarta's chief of police Inspector General Tito Karnavian said a hunt was under way for terror cells believed to be behind the attack.

Three men were arrested near Jakarta early on Friday, police told local media.

A police spokesman Anton Charliyan confirmed on Friday that those who organized the attacks were associated with Daesh terrorist group.

Two of the perpetrators, he added, were "known to have committed similar radical activities some time ago".

Earlier, Bahrum Naim, an Indonesian believed to be fighting with Daesh in Syria, was named as the suspected coordinator.

Karnavian said Naim's "vision" was to unite various Daesh-supporting groups across South East Asia.

Daesh group released a statement saying it had targeted citizens of countries which are part of the international coalition fighting the group, which controls parts of Syria and Iraq.
