At the outbreak of hostilities on February 28, Israel ordered the suspension of activity at two offshore gas fields -- Leviathan and Karish facilities.

Israel's ministry of energy and infrastructure has now announced that production at the Leviathan field has been restored.

"Following situation assessments and examination of all relevant considerations, it was decided at this stage to return the Leviathan rig to operation," a ministry statement said.

The field had been closed over fears that a strike on a pressurised, operational installation could have catastrophic consequences.

Since the war began, Iran has targeted several of Israel's industrial sites, including the oil refinery complex in Haifa.

"The supply of natural gas to the local economy continues and will now be increased following the integration of an additional rig into the production system," the energy ministry said.

Despite wider disruptions to global energy markets following Iran's effective chokehold on the Strait of Hormuz, Israel has remained largely insulated from the ensuing crisis.

Both Jordan and Egypt rely heavily on gas from the Leviathan field.

Amman and Cairo had reportedly requested that Israel resume gas exports.

Israel is said to have rejected their requests, prioritising its own wartime energy security over regional supply commitments.

Following the initial suspension of Leviathan and Karish fields, the Tamar field became the country's sole gas-producing facility.

Producing roughly 11 billion cubic metres (BCM) of gas annually, Tamar nearly covers Israel's entire domestic consumption of 12 to 13 billion cubic metres of gas per year.
