French President returning to France from EU summit after terror attack

Brussels: French President Francois Hollande was to return home early from an EU summit on Friday after a suspected Islamist attack on a factory in eastern France, officials said.

"He will return early this afternoon and is in constant contact with Interior Minister Bernard Cazeneuve and the security services," the official said, adding that he would make a statement to the press in Brussels before 1100 GMT.

French Prime Minister Manuel Valls ordered heightened security measures Friday at "sensitive sites" near the gas factory that was attacked in eastern France.

Valls, who is on an official trip to South America, asked Interior Minister Bernard Cazeneuve to head to Saint-Quentin Fallavier, the site of the attack, the premier's entourage said.
