Alang, which is in Gujarat's Bhavnagar district, is Asia's largest ship dismantling yard where approximately 250 ships are dismantled every year. The ship breaking process uses gas.
"Five persons were killed while seven others sustained injuries after a fire broke out following a blast in the ship which was being dismantled in plot number 140 at the yard," PTI quoted sub-inspector KJ Rathod, posted at Marine Police Station (Alang), as saying.
Prima facie, the blast occurred due to sudden gas leakage when ship-breaking activity was in progress, the officer said.
The exact reason behind the explosion was yet to be ascertained, Rathod told the news agency.
