Unidentified attackers armed with machetes killed a woman and wounded another in central Sulawesi province, where tensions are high following a series of attacks blamed on Islamic militants, police said Saturday. Police said it was too soon to say whether the attack was linked to the simmering sectarian conflict in the Indonesian province, where open battles between Muslims and Christians killed about 1,000 people in 2001 and 2002. The assailants were on motorbikes when they slashed the 20-year-old makeup seller in the neck as she walked home Friday in Palu, the capital of central Sulawesi, said police Lt. Col. Rais Adam. Her companion was injured in the arm, he said. The victims' religions were not immediately known.
