Scores of people in Malaysia were being treated in hospitals on Tuesday after a huge fire broke out at a gas pipeline operated by state energy giant Petronas, showering flaming debris from the sky and shattering windows.

Authorities say a fireball that erupted from a burst gas pipeline soared into the sky outside Malaysia’s largest city and injured 145 people.

Terengganu local government, housing and health committee deputy chairman Saiful Azmi Suhaili said that as most of the methane gas being channelled throughout the peninsula came from the state, there is a lot of pressure on the state government to ensure gas pipelines are safe.
