The pipeline was discovered on the bed of the river Chu, which forms the border between the two countries.

Morette, who is raising about 50 Thanksgiving turkeys this year, has been giving his birds beer since 1993, when he and his workers popped open a few cans after work on a hot July day. A turkey knocked one over and started drinking, he said, and they've been sipping the suds ever since.
Morette, who prefers serving the turkeys lager, insists the beer makes birds fatter, more flavorful and juicier.
"Oh, yeah, it's noticeable," he said. "It's not a strong, gamey flavor, it's a nice turkey flavor."
