Hyderabad, Aug 29 (IANS): The toll in last week's blast at the Hindustan Petroleum Corporation Limited (HPCL) refinery in Visakhapatnam rose to 17 with three more injured succumbing to burns Thursday, an official said.

With this, six injured have lost the battle for life at three different private hospitals during the last two days.

Eight people were killed and 34 injured in the fire caused by the huge blast in the cooling tower which was under construction in the refinery's diesel hydro sulphurisation expansion project.

The HPCL authorities Wednesday handed over a cheque of Rs.2 crore to district collector for handing over Rs.20 lakh each to the kin of 10 contract workers. HPCL has announced Rs.1 crore compensation for its executive killed in the mishap.

The compensation for six workers who succumbed during last two days will be handed over later.
