Tension in far-flung villages escalated early this week when MILF rebels stopped personnel of the provincial engineers office from finishing the final stretch of the five-kilometer, farm-to-market road in Barangay Iganagampong.
The rebels crippled their bulldozer with a B-40 rocket and set it on fire, authorities said.
Last Saturday, civilian volunteer Morris Upam, who was guarding road-building equipment in a nearby barangay, was gunned down, according to Maj. Julieto Ando, spokesman of the Armys 6th Infantry Division.
Dozens of government workers involved in infrastructure projects here, including the widening of the 80-kilometer Maguindanao-Sultan Kudarat Highway, now 52 percent complete, have threatened to abandon their work if the harassment continues.
Maguindanao Gov. Datu Andal Ampatuan said the rebels may possibly mount more attacks once the police file criminal charges against those responsible for the burning of the provincial governments D65 Caterpillar bulldozer.
"They have been identified and the police are now wrapping up its investigation into the incident," he said.
Ampatuan said he is certain that the rebels are bent on sabotaging the infrastructure projects because they fear that the military will gain access to their territories with the construction of new roads.
But Eid Kabalu, speaking on the MILFs behalf, said the attackers could be members of a "lost command" group.
"The police and the military must investigate these problems deeper to identify the real culprits," he said.
