Protesters Surround U.S. Ambassador's Car

The U.S. ambassador to China, Gary Locke, was surrounded in his official car by a group of about 50 Chinese protesters outside the U.S. Embassy on Tuesday and had to be protected by Chinese security guards, a State Department representative said.
The protesters caused minor damage to the vehicle, but Mr. Locke was unharmed, the representative said in a statement.
"Embassy officials have registered their concern regarding today's incident with the Chinese Ministry of Foreign Affairs, and urged the Chinese Government to do everything possible to protect American facilities and personnel," the statement said.
The statement gave no details about the demonstrators who blocked Mr. Locke's car, and what motivated their action, the Wall Street Journal reported.
