PARIS: Gunmen and bombers attacked busy restaurants, bars and a concert hall at locations around Paris on Friday, killing dozens of people in what a shaken President Francois Hollande described as an unprecedented terrorist attack. The death toll has risen to 140 in a series of attacks

Police sources said at least 40 people were killed and 60 wounded in up to five attacks in the Paris region. French media reported higher unofficial death tolls.

The apparently coordinated gun and bomb assault came as the country, a founder member of the U.S.-led coalition waging air strikes against Islamic State fighters in Syria and Iraq, was on high alert for terrorist attacks ahead of a global climate conference due to open later this month.

Hollande, who was attending an international soccer match with German Foreign Minister Frank-Walter Steinmeier when several explosions took place outside the national stadium, declared a state of emergency in the Paris region and announced the closure of France's borders to stop perpetrators escaping.

"This is a horror," the visibly shaken president said in a midnight television address to the nation before chairing an emergency cabinet meeting.

All emergency services were mobilized, police leave was canceled and hospitals recalled staff to cope with the casualties.
