Indonesian police have fired warning shots to disperse a protest by thousands of supporters of Indonesia's President Abdurrahman Wahid for a second consecutive day.
Police in the town of Lamongan say a mob of about 10,000 people tried to attack a local office of the rival Golkar Party, which once supported former dictator Suharto.
Meanwhile President Wahid plans to visit East Java on Friday in a bid to calm the situation there.
Thousands of pro-Wahid protesters also marched through the ancient city of Yogyakarta.
Witnesses said many in that crowd had threatened the city's Golkar office, too.
Police fired tear gas and warning shots at a massive pro-Wahid crowd that burned a Golkar office in the capital of East Java, Surabaya.
Other Golkar offices have been attacked in the region.
The President, who is facing corruption allegations, has called for calm and describes the attacks as "understandable" and a reflection of popular anger against the actions of the legislature.
He has denied the accusations of corruption.
