The Indonesian government decided yesterday to extend martial law in Aceh, where 40,000 members of the Indonesian army have been waging an attack since May on members of an independence group. President Megawati Sukarnoputri had originally said that martial law would only last six months. The Washington Post estimates that the Indonesian military has killed 900 members of the Free Aceh Movement since May. During the same period, 60 Indonesian military and police personnel have been killed.
