A reactor blast at the Kukatpalli-based Gulf Oil Corporation Explosives division took the life of three casual labours and injured at least 12 others.
The blast took place around 8 pm during the supper break, limiting the extent of the impact to only few that stayed near the unit. The roof of the D-1 unit where the blast occurred has collapsed causing grievous injuries to the employees who were present there.
However, security at the Gulf Oil Company refused to allow the media inside or provide details of the deceased.
As a result relatives of the employees started rising slogans against the management and demanded information about their dear ones. Meanwhile, Chief Minister N Kiran Kumar Reddy has directed the Ranga Reddy district collector, Police Commissioner of Cyberabadand DG fire services to immediately take up rescue operations.
