Iraqi officials say they have approved plans to build a five-star hotel in the Baghdad’s heavily guarded Green Zone.

Iraq’s National Investment Commission says land for the project is being leased by the Summit Global Group, a U.S.-based investment company.

Robert Kelley, head of Summit Global, says the 300-room hotel will cost $100 million. He says American and Iraqi investors are involved in the project, but he did not name them.

At a groundbreaking ceremony on Saturday, Kelley said construction would begin soon, but he did not specify a date.

Iraqi government offices and American diplomatic and military facilities are inside the Green Zone, also known as the International Zone.
