Casualties reported as 2 blasts hit bus terminal in Jakarta

Salam's wife reportedly told investigators that the bombs were assembled by another militant known as "Agus", who is now sought by police and considered "at large and risky".

The terminal may have been targeted for its increased police presence, with extra officers deployed ahead of a torch rally to celebrate the start of the Islamic holy month of Ramadan, authorities said.

No one has yet claimed responsibility for the explosions.

They also took a DNA sample from the mother of a second suspect, another 30-year-old Bandung man.

Police are still verifying the personal information of the alleged attacked, the source added.

President Joko Widodo said on Thursday that he had ordered a thorough probe and was "urging all citizens across the nation to stay calm and remain united".

Police officers inspect the site where explosions reportedly went off near a bus terminal in Jakarta, Indonesia, Thursday, May 25, 2017.

On Wednesday night, heavily armed police cordoned off the area around the bus station with tape to hold back hundreds of onlookers while bomb disposal officers with protective suits examined the area.

Numerous recent IS-linked plots in Indonesia have been botched or foiled, with analysts saying that many of the country s militants lack the capacity to launch serious attacks.

Australia's opposition leader Bill Shorten condemned the Jakarta attacks as "absolutely despicable".

Two suicide bombers attacked the busy terminal in the capital late Wednesday in a dramatic assault that sparked panic and left human body parts and shattered glass strewn across the street.

One of the casualties was a police officer while the other is suspected to be the bomber.

The policemen had assembled to escort a scheduled parade organised by a community group in the neighbourhood when the explosion was heard, said the police. Just days before the fasting month was to end, a suicide bomber riding a motorcycle blew himself up after he was stopped outside the local police headquarters. A police inspector said that "aluminum, nails, buckshot, and receipts for purchasing rice cookers" were found at the scene of the attack. Police said an anti-terror squad subsequently raided two houses believed to be owned by the perpetrators in neighbouring provinces of Banten and West Java.

Authorities in the world's biggest Muslim-majority nation are increasingly anxious about a surge in radicalism, driven in part by a new generation of militants inspired by the Islamic State group.
