How has Russia cut supplies?

In May, Gazprom closed a key pipeline which runs through Belarus and Poland and delivers gas to Germany and other European nations.

Then in June, it cut gas deliveries through Nord Stream 1 by 75% - from 170m cubic metres of gas a day to roughly 40m cubic metres.

Then, in July, it shut down Nord Stream 1 for 10 days, citing the need for maintenance.

Shortly after reopening, Gazprom halved the amount supplied to 20m cubic metres because of what it called faulty equipment.

Now it has completely halted all gas supplies to Europe through the pipeline.
