Aerosmith cancels Jakarta concert after bomb threats

US rock band Aerosmith have cancelled a concert scheduled in Jakarta on safety concerns, a concert promoter said, following threats to bomb the Myanmar (Burma) embassy in the Indonesian capital.

"We received the official confirmation yesterday from the Aerosmith management cancelling the May 11 concert in Jakarta over safety concerns," said Sarah Deshita, spokeswoman for co-promoter Ismaya Live on Sunday.

"They gave no specific reasons for the cancellation. We are sad and disappointed over the decision. We did all we could to ensure security was tight and even engaged the marines but it's not enough," she said.

She said 85 per cent of the 15,000 tickets to the concert had been sold.

The band, who recently wrapped up an Australian tour, apologised in the letter of cancellation, which was posted on the promoter's website.

"Aerosmith have been forced to cancel concert ... due to safety concerns," the statement said.

"We want to apologise to all our fans who were expecting to see us and hope that one day we can make it up to them," it added.

Officials on Friday said two Indonesians have been detained over a plot to bomb the Myanmar embassy in Jakarta as radicals rallying in the city called for "jihad in Myanmar" to avenge the death of Muslims in clashes with Buddhists.
