Emotions ran high at the Delhi airport as the anxious wait of several parents to reunite with their children arriving from Ukraine ended in joy with the landing of the third evacuation flight on Sunday morning. On the other hand, scores of parents, whose children are still stuck in the violence-hit country, are having sleepless nights as their children find themselves hiding in bunkers when sirens buzz. The Indira Gandhi International Airport became a witness to a plethora of emotions as parents gave their children a grand welcome with flowers, cards and warm hugs upon their arrival here from the Hungarian capital Budapest.
