Trouble is brewing in the waters off the coast of Lebanon and Israel about the future of one of the largest discoveries of natural gas in the eastern Mediterranean.
A field known as Leviathan might contain 16 trillion cubic feet of gas – enough to serve Israel’s domestic needs and make the country a substantial exporter.
But Lebanon is eyeing some of that income, badly needed to pay off its $50bn national debt. Some Lebanese politicians say the field may extend into their country’s as yet undeclared maritime zone.
Israel and Lebanon are still formally at war and the two neighbours have never agreed a maritime boundary.
Another problem is that Lebanon has not even passed an oil and gas law that would regulate drilling off its coast.
In spite of late night negotiations this week between Saad Hariri, the prime minister, and Nabih Berri, the speaker of parliament, the passage of any such legislation may still be months away.
In the meantime, Israel has unilaterally placed a line of buoys extending two miles into the sea off the two countries’ land border for what it describes as “security reasons”. Lebanon’s government has raised this with the United Nations, fearing that the floating line of Israeli-placed markers may encroach on its maritime territory.
Hizbollah, the armed Shia movement, and its allies have taken up the cause of what they call the defence of Lebanon’s natural resources – and they charge their western-backed political opponents with weakness in regard to the issue.
Mr Berri, from the Shia Amal movement, an ally of Hizbollah, has urged Mr Hariri’s government of national unity to counter what he sees as Israel’s designs on the country’s gas.
“Lebanon’s army, people, and resistance will be ready to thwart any attempt to steal its natural resources,” he said during a visit to neighbouring Syria.
