Thousands of fans waiting in line to enter a concert in South Korea have caused a stampede that killed 11 people and injured at least 60.

The victims were trampled Monday when a near-capacity crowd surged toward a gate at a stadium in the city of Sangju, 270 kilometers south of Seoul.

Among the dead were several young boys and elderly women.

Officials later canceled the concert of South Korean singers popular with older audiences. It was part of festivities for Korea's National Founding Day, marking the legendary date of the country's founding some 4000 years ago.
