China arrested six people over the weekend and shut down at least 16 websites in a sweeping crackdown on Internet speech, especially on microblogs and social networking sites.

The government said it was "cleaning up" the "harmful messages" about "military vehicles entering Beijing," as even comments sections were combed and shuttered.
