After weeks stranded at a closed border in northern Greece, migrants and refugees are seeking out new, irregular routes to get into Macedonia, clambering through forests and over hills under the cover of darkness.

As dusk fell on Saturday evening, a Reuters witness saw a group of up to 70 people crossing into Macedonia from Greece, at a point where there is no razor wire fence between the two countries. They darted in and out of a forest, hiding from authorities.
