LA PAZ, Bolivia (AP) — A protest by Bolivian miners has trapped more than 100 mostly European tourists in the southern Bolivia mining city of Potosi for more than a week.

The protesters piled rocks on the runway of the Potosi airport Friday to prevent a plane from landing to pick up some of the foreign tourists.

The miners have also blocked roads into the area for 10 days.

Also trapped are about 500 Bolivians, and local media say the blockade is beginning to cause food shortages in the city of 200,000 people.

The miners have a series of grievances with the government, including a demand to reactivate mines that officials ordered closed and to settle land disputes.
