Abu Jabber has a plan to escape the Syrian regime’s advance: he has built a ladder from rusty metal for him and his 11 children to climb over the Turkish border wall. Six months ago, the family fled deadly fighting in Idlib province of northwest Syria, seeking shelter near the border village of Kafr Lusin, where dozens of families live in an informal camp for the displaced. Newcomers live in tents while others, like Abu Jabber, his children and his parents, have built makeshift homes at the foot of a cement wall that separates Turkey from Idlib province.
