Aleppo streets 'devastated,' says Syria analyst Michael Weiss

Fierce fighting between Syrian government troops and rebels is taking place in a strategic district of the biggest city, Aleppo.

Images that have emerged from the northern city show buildings reduced to rubble by heavy weapons.

Michael Weiss, a Syria analyst at the Henry Jackson society, was in Aleppo with a rebel contingent briefly last week.

He said the streets were devastated and bore the visible scars of a warzone.
