Amid security concerns, French officials have insisted that preparations to hold the Paris Olympics opening ceremony on the Seine River are still in full swing and will go ahead as planned.

The Paris Olympics open in 100 days and the United States and China are expected to finish 1-2 in the overall and gold-medal count.

Organizers have planned a parade of about 10,500 athletes through the heart of the French capital on boats on the Seine along a 6-kilometer (3.7-mile) route in the opening ceremony at sunset on July 26.

Charities say authorities want to clear homeless people from streets and squats to make city look better for Games
