New Delhi's main domestic terminal is likely to remain shut for a few weeks with debris still scattered outside the airport following last week's roof collapse, two sources with direct knowledge of the matter told Reuters on Monday.

Part of a departure terminal canopy at New Delhi’s main airport has collapsed as monsoon rains lashed the Indian capital, killing one person and injuring six others.

India has seen an infrastructure boom to meet rising demands for transportation, but there have been criticisms about poor maintenance and oversight of building.

Permission to open the new terminal will now be granted only after a comprehensive examination of the structure is completed, which is likely to take over a month.

Delhi Airport was preparing to start operations at a new terminal by middle of July, but now permissions would be granted only after a thorough examination.
