A new report by the watchdog group Human Rights Watch (HRW) claims the Syrian regime is expanding its use of cluster bombs as its battle with opposition forces enters its third year.
The report, citing field investigations and amateur videos, says Syrian forces in the past six months have dropped at least 156 cluster bombs in more than 100 locations across the country.
Cluster bombs, which open in flight, scattering smaller explosive devices, are seen as posing a long-term threat to civilians because many do not explode immediately.
Most countries have banned their use.
The report comes a day after Syrian rebels marked the second anniversary of their uprising against President Bashar al-Assad.
The United Nations says 70,000 people have been killed and 4 million displaced by the fighting.
