Jakarta: Multiple explosions went off and gunfire broke out in the centre of the Indonesian capital on Thursday and police said they suspected a suicide bomber was responsible for at least one of the blasts.

Multiple explosions were heard near the United Nations office and the building has been locked down. No individual or organisation has claimed responsibility for the attacks.

Six people including three police officers are among those killed in the blasts and the death toll is expected to rise. According to CNN sources, police station appeared to be the main target.

United Nations Regional Representative Jeremy Douglas tweeted about blasts near the UN office followed by gunfire.

Media said six bombs went of and a Reuters witness saw three dead people and a gunfight going on. One blast went off in a Starbucks cafe and security forces were later seen entering the building.

"The Starbucks cafe windows are blown out. I see three dead people on the road. There has been a lull in the shooting but someone is on the roof of the building and police are aiming their guns at him," said a Reuters photographer.

According to the official Jakarta police Twitter account one explosion went off in front of a shopping centre called the Sarinah mall, on a main city avenue.

The country has been on high alert after authorities said they had foiled a plot by Islamic militants to attack government officials, foreigners and others. About 150,000 police officers and soldiers were deployed during New Year's Eve to guard churches, airports and other public places.

More than 9,000 police were also deployed in Bali, the site of Indonesia's deadliest terror attack, which killed 202 people in 2002.

National Police spokesman Major General Anton Charliyan said security is focused on anticipating attacks in vulnerable regions, including Jakarta.

On Tuesday, the jailed radical Islamic cleric Abu Bakar Bashir appealed to an Indonesia court to have his conviction for funding a terror training camp overturned, arguing that his support for the camp was an act of worship.

The 77-year-old leader of the Jemaah Islamiyah terrorist network filed a judicial review of his 2011 conviction, when he was sentenced to 15 years in jail for setting up the camp in Aceh province. A higher court later cut the sentence to nine years.

Indonesia, the world's most populous Muslim nation, has suffered a spate of deadly attacks by the Jemaah Islamiyah network in the past. But strikes in recent years have been smaller and less deadly, and have targeted government authorities, mainly police and anti-terrorism forces.
