Veteran fighters of last year’s civil war in Libya have come to the front-line in Syria, helping to train and organise rebels under conditions far more dire than those in the battle against Muammar Gaddafi, a Libyan-Irish fighter has told

Hussam Najjar hails from Dublin, has a Libyan father and Irish mother and goes by the name of Sam. A trained sniper, he was part of the rebel unit that stormed Gaddafi’s compound in Tripoli a year ago, led by Mahdi Al Harati, a powerful militia chief from Libya’s western mountains.

Harati now leads a unit in Syria, made up mainly of Syrians but also including some foreign fighters, including 20 senior members of his own Libyan rebel unit. He asked Najjar to join him from Dublin a few months ago, Najjar said.

The Libyans aiding the Syrian rebels include specialists in communications, logistics, humanitarian issues and heavy weapons, he said. They operate training bases, teaching fitness and battlefield tactics.

Najjar said he was surprised to find how poorly armed and disorganised the Syrian rebels were, describing Syrians in general as far more repressed and downtrodden under Assad than Libyans were under Gaddafi.

“I was shocked. There is nothing you are told that can prepare you for what you see. The state of Syrians — their state of mind, their fate — all of those things have been slowly corroded over time by the regime.”

“I nearly cried for them when I saw the weapons. The guns are absolutely useless. We are being sold leftovers from the Iraqi war, leftovers from this and that,” he said. “Luckily these are things that we can do for them: we know how to fix weapons, how to maintain them, find problems and fix them.” In the months since he arrived, the rebel arsenal had become “five times more powerful”, he said. Fighters had obtained large calibre anti-aircraft guns and sniper rifles.

Disorganisation is a serious problem. Unlike the Libyan fighters, who enjoyed the protection of a Nato-imposed no-fly zone and were able to set up full-scale training camps, the rebels in Syria are never out of reach of Assad’s air power. “In Libya, with the no-fly zone, we were able to build up say 1,400 to 1,500 men in one place and have platoons and brigades. Here we have men scattered here, there and everywhere.”

Although many rebel units fight under the banner of the Free Syrian Army, their commands are localised and poorly coordinated, Najjar said.

“One of the biggest factors delaying the revolution is the lack of unity among the rebels,” he said. “Unfortunately, it is only when their back is up against the wall that they start to realise they should (unite).”

Syria’s uprising has evolved into an all-out civil war with sectarian overtones. Harati’s unit is known as the Umma Brigade, referring to the global community of Muslims. Najjar said thousands more fighters from the Arab world were gathering in neighbouring countries prepared to join the cause.

Harati is reluctant to enlist them because he does not want his cause tarnished by the perception that foreign militants are linked to Al Qaeda, Najjar said, but he said that many of the foreigners were making their way to Syria on their own.

The Umma Brigade’s Facebook page shows a picture of Najjar aiming his rifle in what looks like an open field. In another he is posing with Harati and rebels. A YouTube video shows Harati leading an attack on a checkpoint in Maarat Al Numan in Syria.

Najjar said militancy would spread across the region as long as the West does not do more to hasten the downfall of Assad.

“The Western governments are bringing this upon themselves. The longer they leave this door open for this torture and this massacre to carry on, the more young men will drop what they have in this life and search for the afterlife,” Najjar said.

“If the West and other countries do not move fast it will no longer be just guys like me - normal everyday guys that might do anything from have a cigarette to go out on the town — it will be the real extreme guys who will take it to another level.”
