Jacqui Southey: Save the Children advocate on the death toll from the earthquakes in Turkey and Syria - Heather du Plessis-Allan Drive

Fears countless children may be trapped under rubble after devastating earthquakes in Turkey and Syria.

At least 4300 people have died since the catastrophic 7.8 magnitude quake yesterday.

Just over an hour ago, another 5.6 magnitude earthquake rocked Central Turkey in one of more than 130 aftershocks.

Well over 5000 buildings have collapsed in Turkey alone.

Save the Children's Jacqui Southey says children separated from their families will need help, including shelter in the freezing conditions, warm clothing and medical care.
