Indonesia's state-managed news agency is reporting that anti-terrorism police have shot and killed five suspected Islamist militants in eastern Indonesia.

The raids on Friday night and Saturday morning on Sumbawa followed the killings of two suspected militants earlier Friday on Sulawesi island, also in the east of the country.

Antara reported that the country's elite anti-terror squad carried out the operations and that they were linked to the raid in Makassar.

Police were not immediately available for comment.

Indonesia was hit by four major al-Qaida-linked bombings between 2002 and 2009, but a sustained police crackdown is thought to have reduced the threat significantly.

However, small groups of local terrorists have carried out several attacks on police around the country over the last two years.
