BEIRUT           -               Protesters prevented Lebanon’s parliament from holding its first session in two months on Tuesday, escalating a wave of demonstrations against rulers blamed for steering the country towards economic collapse.

Banks reopened after a one-week closure, with police stationed at branches and banks applying restrictions on hard currency withdrawals and transfers abroad.

The protests erupted last month, fuelled by corruption among the sectarian politicians who have governed Lebanon for decades. Protesters want to see the entire ruling class gone from power.

Lebanon’s economic troubles have increased since then. Despite the depth of the economic crisis, the worst since the 1975-90 civil war, politicians have been unable to form a new government since Prime Minister Saad al-Hariri quit on Oct. 29.

Near parliament on Tuesday, gunfire was heard as several dozen protesters forced two SUVs with official plates and tinted windows to turn back as they approached the building, Lebanese television showed.

The vehicles sped away after they were struck by demonstrators chanting “Out, out, out!”

Parliament postponed the session indefinitely. “This is a new victory for the revolution and we are continuing until we achieve our goals,” said protester Abdelrazek Hamoud.

The session’s agenda had included reelecting members of parliamentary committees and discussion of an amnesty law that would lead to the release of hundreds of prisoners. Protesters were angry the MPs were not tackling their demands for reform.

Security forces had fanned out before dawn, shutting down roads around parliament with barbed wire. Police scuffled with protesters who tried to remove a barbed wire barricade.

Ahmad Mekdash, a civil engineer, said: “They should be meeting right now to form a new cabinet and not to pass laws, especially laws that aren’t urgent.”

The economic crisis, rooted in years of government waste and corruption, has now filtered into the financial system which faces dollar shortages and a weakening of the pegged pound. Banks had mostly been closed since the protests started.

Though the banking association on Sunday had agreed a weekly cap of $1,000 on cash withdrawals from U.S. dollar accounts, some depositors found they could only withdraw a lesser amount.

Six customers at Bank Audi were told they could only take out a maximum of $300. Several customers at BankMed were told the cap was $400. A banking source said the $1,000 figure had been set as a ceiling and for some customers it was less depending on the amount in their account.

“I have an account with $8,000 dollars and they won’t let me withdraw above 300. They told me you can take $1,000 out only if your account has above $100,000 in it,” said Bank Audi customer Charif Baalbaki, 43, a copywriter.

Bank of Beirut customer Khalid Maarouf, 40, who works in textiles, said he didn’t know how he was going to come up with dollar payments he needed to make this month. “I need $20,000 before the end of the month to make payments to people and I can only get $1,000 each week,” he said. Caretaker finance minister Ali Hassan Khalil said Lebanon was in “a critical condition” requiring a new government. But in the last few days he said there had been “no real new effort” towards forming one.

Hariri, who is aligned with Western and Gulf Arab states, wants to return as prime minister of specialist ministers devoid of any other politicians, while the Iran-backed Hezbollah and its allies say the gvernment should include politicians.
