Mohawk demonstrators have taken over an eastern Ontario quarry on disputed land.

About 70 people, some dressed in army fatigues and some carrying colourful Mohawk flags, blocked the entrance of the Thurlow Aggregates quarry near Deseronto, Ont., late Thursday afternoon.

The demonstrators' spokesman Shawn Brant said they plan to stay until the province cancels the quarry's licence. Since November Mohawk leaders and the federal government have been involved in discussions and negotiations over the land, which the Tyendinaga Mohawks have claimed.

"It's very difficult to carry out meaningful negotiations at the table while they're taking out 10,000 truckloads a year of our land," Brant said, adding that the protest could last several days and possibly expand into the town of Deseronto.

The land claim consists of more than 400 hectares on the Bay of Quinte, east of Belleville, including the sites of many businesses such as the quarry.

Chief Don Maracle said band councillors won't sanction the protest, but he added, "The Mohawk council certainly understands the frustration young people have in achieving a resolution that's in the best interest of future generations."

Deseronto Mayor Norm Clark said he is disappointed that the protest is taking place.

"If they're going to continue there and set up camp I would hope the police would take care of that situation," he said.

Mohawk police said they have no plans to stop the demonstration as long as it remains peaceful.
