(Qalamoun, AFP) On a windy hilltop overlooking the mountainous Syrian border, a fighter from Lebanon’s Hezbollah terror group says the battle against Syrian rebels in the area is among the toughest the group has ever faced.  

The powerful Shia Islamist movement, a key ally of the Assad regime in Damascus and Iran’s strongest proxy in the region, has fought across Syria in the years since an uprising began in 2011.

In the past two weeks, Hezbollah says it has secured around a third of the Qalamoun region, territory on both the Lebanese and Syrian sides of the porous border.

“This is one of the hardest battles we have fought,” said a Hezbollah fighter in Qalamoun, who spoke on condition of anonymity.

“Everyone knows that fighting in the mountains is the hardest kind of fighting there is, up there with fighting in cities.”  

The area of roughly 1,000 square kilometers is a landscape of imposing hillsides riddled with caves, and open valleys full of scrub and wildflowers.  

“This is the most difficult battlefield in the Middle East right now,” nodded another fighter, dressed like many in the area in desert-tone camouflage.

The fate of Qalamoun is particularly important for Hezbollah, which has long defended its intervention in Syria alongside President Bashar al-Assad’s troops as key to the security of Lebanon.  

‘To protect Lebanon’

In Qalamoun, that argument carries more weight because of the presence of jihadists from the Islamic State group (ISIS) and Al Qaeda affiliate Al-Nusra Front.  

The two groups have infiltrated Lebanon in the past, and last August briefly overran the eastern Lebanese border town of Arsal.  

They are still holding 25 soldiers and policemen hostage, and have executed four captives.  

“Our goal in Qalamoun is to protect Lebanon, and we’ve seen the evidence of the threat in Arsal and the other attacks on the border,” a Hezbollah commander said.

In recent days, Hezbollah has provided unprecedented but carefully orchestrated media access to its fighters and positions in the Qalamoun region.

The tours begin with a briefing by a military commander, who uses a green laser pointer to illustrate on a projected digital map the necessity of securing the high ground to ensure line-of-fire sight over the area.

On the ground, an array of fighters lead convoys of journalists in SUVs across rocky terrain with little sign of life beyond a few birds and a scrambling lizard or two.

The trips include stops at bunkers captured from Sunni rebels, where Hezbollah is eager to show the remains of homemade explosives, and cautious interactions with fighters, many of whom preferred to observe the visitors from a remove, some smoking quietly.  

The outreach is a new approach for Hezbollah, which has generally preferred to keep coverage of its involvement in Syria’s conflict confined to its official media outlets.

One member of the group said the new campaign was an attempt at both “psychological warfare” but also a form of public relations.

“This is psychological warfare that we hope will make the enemy afraid, but it’s also a way for us to send our message to say that we’re the good side.”  

That assertion is contested by Syria’s opposition, which accuses Hezbollah of facilitating Damascus’s brutal attempts to put down an uprising that began with peaceful protests and spiraled into a war after a regime crackdown.

But while Hezbollah is listed as a terrorist organisation by Washington, it is now fighting against some of the same jihadist groups being targeted by US-led air strikes in Syria and Iraq.

Evidence of battles

The Lebanese and Syrian armies are conspicuous by their absence in Qalamoun.

Hezbollah members avoid comment on the Lebanese army’s role in the region, and insist Syria’s army leads the fight inside its country.

“We fight from the Lebanese side and they fight from the Syrian side,” a Hezbollah fighter identified as Hajj Nader said, standing several kilometers inside Syrian territory.

At several sites in the region, the evidence of battle was strewn on the ground.  

Heavy machine gun casings and tubes that once held rocket shells lay alongside metal ammunition cases, their lids peeled back like sardine tins.

At some positions, Hezbollah fighters fired into the distance, and explosions they said were mines being cleared could be heard.

The fighters carried weapons included pistols, Kalashnikov rifles and at least one M4 mounted with a grenade launcher.

Some sported patches on their uniform invoking Shia religious figures and Hezbollah’s leader Hassan Nasrallah.  

“These aren’t required. Everyone puts on what they want. You see, we’re not an army, we’re just regular guys,” one fighter said.

Since officially announcing its active participation in the Syrian civil war in support of the regime of Bashar al-Assad at Iran’s behest, Hezbollah has lost hundreds of fighters, possibly more, in that war alone. Hezbollah manpower has also been deployed in Iraq and, according to numerous reports, in Yemen as well.

The battle for Qalamoun has been particularly bloody, with rebels fighting tooth-and-nail to preserve a key supply route to allies in Lebanon. Scores of Hezbollah fighters have been killed in the fighting, including at least one senior military commander.

Hezbollah leader Hassan Nasrallah has vowed to defeat Syrian rebels, whatever the cost, declaring that a defeat for Assad would ultimately lead to the demise of Hezbollah.

Hezbollah’s costly commitment in battlefield outside Lebanon – coupled with the need to maintain its presence within Lebanon itself – has also placed severe strain on its finances, although despite dire predictions it appears its Iranian sponsors are still able to keep it afloat.
