A Molotov cocktail was thrown at Myanmar embassy in the Indonesian capital of Jakarta in the early hours of Sunday, causing a small fire, reports Reuters.
This comes amid mounting anger in the Southeast Asian nation, home to the world's biggest Muslim population, over violence against Rohingya Muslims in Myanmar.
A police officer patrolling a street behind the embassy spotted a fire on the second floor of the building and alerted the police officers guarding the front gate of the embassy, Jakarta police said in a statement on Sunday.
After the fire was extinguished, police found a shattered beer bottle with a wick attached to it, the statement said, adding that the unknown perpetrator is suspected to have driven away from the scene in an MPV car.
Jakarta police were currently investigating the incident, said spokesman Argo Yuwono. The police were yet to find out the motive behind the attack.
A group of activists on Saturday held a protest at the embassy calling Nobel Prize Committee to withdraw the Nobel Prize from Myanmar leader Aung San Suu Kyi, the state news agency Antara wrote.
Protests continued on Sunday in Jakarta's city central, with dozens of people under Islamic groups and activist groups calling Indonesian government to be actively involved in solving the human rights violation against the Rohingya community.
The treatment of Buddhist-majority Myanmar's roughly 1.1 million Muslim Rohingya is the biggest challenge facing Aung San Suu Kyi, accused by Western critics of not speaking out for the minority that has long complained of persecution.
Aid agencies estimate about 73,000 Rohingya have fled into neighbouring Bangladesh from Myanmar since violence erupted last week.
