Pakistan, a country with large reserves of natural gas, is suffering from a shortage of the resource amongst industries, who rely on it to generate power.

The knock-on effect from the industries shutting down for long periods is that millions are going without work, in an economy that is already reeling from multiple shocks.

The latest gas shortage has led to widespread protests against the government, particularly in central Punjab, the heartland of Pakistan's industries.
