Ten people have been killed, and more than 30 injured, in a bomb blast at a New Year music concert in the Indonesian province of Aceh.
Indonesia declared martial law in Aceh last May
Military officials said the bomb destroyed the open-air stage in the town of Peureulak, midway through the concert attended by many teenagers.
A one-year-old girl and a seven-year-old boy were said to be among the dead.
The Indonesian army blamed the blast on Aceh separatists, but a rebel spokesman denied they would target civilians.
An eyewitness, who said his name was Ahmad, said the blast badly damaged the stage and blew apart the musical instruments.
"After several songs suddenly there was a loud bang. People panicked and ran," he was quoted by French news agency AFP as saying.
Military spokesman Lieutenant Colonel Ahmad Yani Basuki said most of the dead were teenagers.
"The explosion took place at 2220. It was very powerful," he told AFP.
Mr Basuki blamed rebels of the Free Aceh Movement (Gam) for the attack.
But a local rebel commander, Ishak Daud, denied Gam's involvement.
"We have never targeted civilians because they are our people," he told AFP.
The Indonesian Government placed Aceh under martial law on 19 May 2003, and launched a crackdown on the separatists who have been fighting for the province's independence since 1976.
