Living underground has become the norm in Syria's opposition-held enclave of Eastern Ghouta, with some families in basements for the past month, some containing 200 people, said Christophe Boulierac of the U.N. Children's Fund (UNICEF) said on tuesday.
At least 1,000 children have reportedly been killed or seriously injured across Syria so far this year, he said.
The United Nations said that it planned to send another aid convoy to Syria's besieged enclave of 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 jeopardising the safety of humanitarian teams on the ground," Jens Laerke of the U.N. Office for the Coordination of Humanitarian Affairs (OCHA) told a news briefing on Tuesday.
