Syrian government jets 'drop chlorine bombs' on crowded Aleppo neighbourhood

Syrian government aircraft have dropped suspected chlorine bombs on a crowded neighbourhood in Aleppo, injuring dozens, according to rescue workers in the contested city.
Ibrahem Alhaj, a member of the Syria Civil Defence first responders team, said he got to the scene of the suspected gas attack shortly after a helicopter dropped barrels containing what he said were four chlorine cylinders.
