Jakarta: Indonesian authorities flew 14 alleged terrorists from Aceh to Jakarta on Friday, hours after raiding another group of suspected Islamic militants in the restive province.
Police said they were investigating possible links to a terrorist threat to shipping.
A police officer was killed and at least 10 were wounded in the raid Thursday in Aceh's Lamkabeue village, provincial police chief Maj. Gen. Aditya Warman told reporters.
Police were investigating whether the militants were linked to a threat to shipping in the nearby Malacca Strait, national police chief Gen. Bambang Hendarso Danuri said in Jakarta, without elaborating.
Singapore's navy warned this week that an unnamed terrorist group was planning attacks on oil tankers in the strait, one of the world's busiest shipping lanes.
Danuri said there were casualties among the militants, but declined to give details.
The battle came during a police crackdown on militants in Aceh suspected of being linked to the Southeast Asian terror network Jemaah Islamiyah.
Police announced Thursday that they have charged 14 suspected militants arrested in Aceh with planning terrorist attacks.
They were flown from Banda Aceh on Friday to national police headquarters in Jakarta for further questioning, a police official said on condition of anonymity.
