SHANGHAI (AFP) - Tropical Storm Nanmadol lashed China Tuesday, forcing tens of thousands of boats back to harbour and causing the cancellation of dozens of flights, officials and state media said. Nanmadol, which was downgraded to a tropical storm from a typhoon on Monday, earlier left a trail of destruction in Taiwan and killed at least 16 people in the Philippines. Chinese weather authorities said Nanmadol was close to making landfall in Fujian on Tuesday.
