Indonesia ? Indonesian officials acknowledged Saturday that relief aid meant for those left homeless by a deadly earthquake was mistakenly distributed to people who did not need it.

Officials said many people collected aid at relief centers in cities after the quake, even though their homes were not destroyed. As a consequence, others in more remote areas who lost their homes were not able to get sufficient aid.

Many villagers have complained of dwindling food rations following Tuesday’s temblor that killed more than 70 on western Sumatra island.

Solok District Chief Gusmal Effendi called the mix-up a “technical problem,” and promised aid would soon reach everyone displaced by the disaster.

Early surveys found up to 15,000 houses were badly damaged or destroyed by the 6.3 magnitude temblor and a strong aftershock, said Jules Korsten, West Sumatra emergency coordinator for the U.N. International Organization for Migration.
