Syria civil war: Up to 70,000 refugees head to Turkey

Turkish Prime Minister Ahmet Davutoglu said up to 70,000 may be heading to the border, while a monitoring group put the number at about 40,000.
Intense Russian air strikes have helped Syria's government troops make advances near the country's largest city.
Meanwhile, Russia accused Turkey of preparing an invasion into Syria.
Also on Thursday, a Saudi military spokesman said the country is ready to send ground troops to Syria to fight the so-called Islamic State group. LINK
