Syria's suffering revealed in satellite images
The "terrible human suffering" inflicted on the people of Syria has been revealed in satellite imagery, the UN's Institute for Training and Research (Unitar) says.
Markets, power supplies, schools and hospitals are among sites destroyed amid the country's conflict, Unitar's analysis of the images found.
The organisation has published a full report on the damage caused by the four-year-long war, which it says "depicts with no uncertainty the terrible human suffering to which the people of Syria are exposed".
Homs, Syria's third largest city, has been a key battleground in the conflict and has suffered much destruction.
Schools in the Al Hamidiyah neighbourhood have been damaged and one has been completely destroyed. The area around the Khalid ibn al-Walid Mosque, one of the most famous mosques in Homs, has also been a target of numerous attacks.
