Smoke rises over the al-Qadam district of the Syrian capital Damascus. Videos obtained from social media websites show the aftermath of attacks here and elsewhere across the country. Reuters cannot independently verify the content of the videos. In al-Raqqah, west of Aleppo, an aircraft is seen flying overhead before a thick plume of smoke billows from a building in the distance. The fighting in Syria has been going on for 22 months now, and it's not just the death toll which keeps rising.
