Army clashes with Hezbollah, Amal supporters in Beirut

Supporters of Shiite groups Hezbollah and Amal clash with police overnight after spread of video insulting Shiite figures and the parties' leaders.

BEIRUT - Dozens of people were wounded in overnight clashes between security forces and supporters of Lebanon's two main Shiite political parties, the civil defence said on Tuesday.

It was the latest incident of violence in what have been largely peaceful protests since October 17 against a political class deemed inept and corrupt.

The street movement pushed the prime minister to step down on October 29, but the country's bitterly divided political parties have failed to agree on a successor.

Shortly before midnight on Monday, young supporters of Shiite political parties Hezbollah and Amal tried to attack the main anti-government protest camp in central Beirut.

The angry young men arrived on foot and scooters, apparently fired up by a video shared online that they deemed offensive to Shiites.

The video, which inflamed passions in a country where sectarian divisions run deep, was purportedly made by an expatriate Lebanese Sunni from the northern city of Tripoli and released on social media.

In the vicinity of the area close to a main road that links the capital's eastern and western sections, scores of youths had burnt tyres, smashed office buildings and torched several cars, live coverage by local television stations showed.

They lobbed stones and fireworks towards the anti-riot police trying to prevent them from entering the largely empty main square. The security forces responded with teargas and a water cannon.

The protesters camped in the square have been targeted by Shiite groups in the past angered by chants against their political leaders, although Tuesday's violence was of an overtly sectarian nature.

Civil defence said 23 people were taken to hospital, while 43 were treated at the scene. It was not immediately clear from which side the wounded were.

In the southern city of Sidon, groups of masked youths stormed into a main square where they set ablaze several tents set up by demonstrators who have camped for weeks, local television stations said.

Lebanese academic Imad Salamey said the Monday night clashes could have been an attempt to undermine the protests.

"Stirring sectarian strife is one of the ways used by those in power to divide Lebanese and weaken the street movement," he said.

But "the economic crisis today reflects a complete regime crisis that cannot be solved or faced with sectarian movements", warned the professor at the Lebanese American University.

Crumbling economy

Lebanon's economy is sliding towards collapse, after years of political deadlock compounded by the outbreak of civil war in neighbouring Syria in 2011.

The World Bank projects it will contract by more than 0.2 percent this year.

It has warned that poverty could shoot up from a third to half the population if the deadlock is not resolved.

Salamey said solidarity between Lebanese has only increased "after people started losing their jobs and companies and being unable to withdraw money from the banks".

"The economic crisis has broken the barrier of fear, or at least the barriers between different religious sects," he said.

The international community has urged Lebanon to speed up the formation of a new government to implement economic reforms necessary to unlock billions of dollars in foreign aid.

Prime minister Saad Hariri stepped down under street pressure less than two weeks into the protests.

But nearly seven weeks later, no consensus has yet been reached on a replacement and parliamentary consultations to name a new premier have twice been postponed, the latest on Monday.

Young Hezbollah and Amal supporters have attacked anti-government demonstrators on several occasions over the past two months, mostly angered by what they viewed as insults to their leaders.

But the protests themselves have been mostly peaceful - with the exception of some unprecedented clashes at the weekend.

On Saturday, demonstrators threw water bottles and firecrackers at the security forces who responded with tear gas and water cannons.

On Sunday night, a new round of clashes erupted for several hours, though less violent than the previous night.
