Children carry placards during an anti-government demonstration near a Red Crescent aid convoy in the rebel held besieged town of Jesreen, Ghouta.

:: At least 1,000 children have been killed across Syria so far this year, said Christophe Boulierac of the United Nations Children’s Fund (UNICEF).

He said that living underground has become the norm in the besieged rebel-held enclave of eastern Ghouta where 400,000 people live.

The UN said that it planned to send another aid convoy to eastern Ghouta on Thursday, after 14 of 46 trucks were unable to fully unload on Monday due to shelling on the town of Douma.

“After nearly nine hours inside, the decision was made to leave for security reasons and to avoid jeopardizing the safety of humanitarian teams on the ground,” Jens Laerke of the UN Office for the Coordination of Humanitarian Affairs (OCHA) told a news briefing on Tuesday.
