Tribesmen shoot down Yemeni army helicopter, 9 dead

At least nine Yemeni military personnel were killed on Tuesday when tribesmen shot down an army helicopter in central Yemen where gunmen had repeatedly blown up oil pipelines, a military source said.

The government has been frustrated by repeated attacks on Yemen's main oil export pipeline, often carried out by disgruntled tribesmen seeking personal gain or trying to force authorities to release jailed relatives. (Reuters)
