Indonesian police have arrested several people suspected of terrorist acts.
The arrests were reportedly connected to the 2002 Bali attacks
Police chief Da'i Bachtiar refused to identify them, saying they were held under anti-terrorism laws that allow for a week's detention without charge.
The Jakarta Post said 24 people had been arrested recently in connection with the 2002 Bali bombings and a 2003 attack on Jakarta's Marriott hotel.
Dozens of people have already been tried over the attacks, but police say other suspects remain at large.
Police say both attacks were the work of Jemaah Islamiah, a militant Muslim organisation that wants to set up a unified Islamic state across South East Asia.
According to the Jakarta Post, the latest suspects were detained as a result of raids in connection with bombings in May in Poso, Central Sulawesi, that killed 22 people.
The paper said several of the people arrested had been preparing to travel to the Philippines.
