Two days after U.S.-led forces launched a bombing campaign on Afghanistan, six Air Self-Defense Force C-130 cargo planes arrived in Islamabad with relief supplies for refugees.

Because of the planes' short range, 140 SDF members took four days to airlift 315 tents, 200 blankets and other goods there.

Both opposition lawmakers and SDF officers want to know why the government did not charter civilian aircraft that could have transported a larger amount of supplies within a single day.
