By JOHN LEICESTER PARIS (AP) — The Paris Olympics were getting off to a rough start Friday, with suspected acts of sabotage targeting France’s flagship high-speed rail network and cloudy skies and forecast rains over the French capital ahead of its sprawling, ambitious opening ceremony. On a day of utmost importance for France and its capital, with dozens of heads of state and government in town for the Olympic opening and a global audience topping 1 billion expected to tune in, authorities were scrambling to deal with widespread rail disruptions caused by what they described as coordinated overnight sabotage of high-speed train lines. Overcast skies over Paris further dampened the mood.
