Jakarta. The civilian death toll from Thursday's terrorist attack in Central Jakarta has risen to three after the overnight death of an office worker who had been in a coma since the incident.

Rais Karna, a 37-year-old office worker at the Bangkok Bank, a block north from the site of the blasts, was being treated at the Abdi Waluyo Hospital in Central Jakarta after he was was shot in the head by an attacker.

“Rais died on Saturday at 9:21 p.m.,” the Jakarta Regional Police told state-run news agency Antara via a text message on Sunday.

Rais' body was returned to his family in Bojonggede, Bogor, in the early hours of Sunday where a service will be held.

A local identified as Rico Hermawan and Canadian national Amel Quali Taher were both killed instantly at the scene of the blasts at the intersection of Jalan M.H. Thamrin and Jalan K.H. Wahid Hasyim, near the Sarinah department store.

The death toll now stands at eight — four confirmed perpetrators, three civilians and one man whose role police are still trying to confirm. The incident injured 32 people.

At least five explosions were heard coming from the Starbucks outlet at the Skyline building next to Sarinah and the police post in front of the department store around 10:50 a.m. on Thursday.

The blasts were quickly followed by a sporadic exchange of gunfire between the assailants and police.

Police have identified Bahrun Naim, an Indonesian jihadi based in Syria with the Sunni militant group Islamic State, as the mastermind behind the plot. Islamic State supporters have also claimed responsibility for the attack.
