The International Comimttee of the Red Cross (ICRC) called on all sides on Friday to continue the evacuation operation which was suspended hours earlier.

“Regretfully the operation was put on hold. We urge the parties to ensure it can be relaunched & proceed in the right conditions,” Robert Mardini, ICRC regional director for the Near and Middle East tweeted.

No further details were given.

More than 40 wounded people and around 3,000 civilians including children and women were evacuated from east Aleppo on Thursday in two evacuations, the ICRC said in a statement.

Mardini stated that “many more” rotations of buses and ambulances might be needed in coming days.
