Families who fled Syrian government and Russian strikes in northwestern Syria are sleeping in an Olive Grove near the Turkish border, without enough food and no place else to go.

They are some of the 150,000 people who have escaped a surge in violence in the last major Syrian rebel stronghold in the last few weeks.

It marks the most intense escalation between president Bashar al-Assad and his rebel since last summer, with dozens killed in the shelling of insurgent areas.

There is no room for displaced families at the nearby camp in the town of Atmeh.

Some have made makeshift tents by stringing sheets between trees and infants sleep under mosquito nets suspended from the branches.
