South Korean farmers, who say free trade hurts them, swung sticks and hurled eggs. Police responded with pepper spray and water cannons.
Reports say more than 50 people, including five police officers, were hurt and more than 900 others were arrested.

Diplomats say a failure to resolve sticking points before the six-day talks end tomorrow could jeopardize the chances of freeing up global business in farm and industrial goods and services.
