ReutersKurds seize Iraq/Syria border post; Sunni tribe joins fight against Islamic StateBy Isabel Coles and Jonny HoggIraqi Kurdish troops drove Islamic State fighters from a strategic border crossing with Syria on Tuesday and won the support of members of a major Sunni tribe, in one of the biggest successes since U.S. forces began bombing the fighters.
The victory, which could make it harder for militants to operate on both sides of the frontier, was also achieved with help from Kurds from the Syrian side of the frontier, a new sign of cooperation across the border.
Iraqi Kurdish peshmerga fighters took control of the Rabia border crossing in a battle that began before dawn, an Iraqi Kurdish political source said.
"It's the most important strategic point for crossing. Once that's taken it's going to cut the supply route and make the operation to reach Sinjar easier," the source said, referring to a mountain further south where members of the Yazidi minority sect have been trapped by Islamic State fighters.
The participation of Sunni tribal fighters in battle against Islamic State could prove as important a development as the advance itself.
Members of the influential Shammar tribe, one of the largest in northwestern Iraq, joined the Kurds in the fighting, a tribal figure said.
"Rabia is completely liberated. All of the Shammar are with the Peshmerga and there is full cooperation between us," Abdullah Yawar, a leading member of the tribe, told Reuters.
He said the cooperation was the result of an agreement with the president of Iraq's Kurdish region after three months of negotiation to join forces against the "common enemy".
Gaining support from Sunni tribes, many of which either supported or acquiesced in Islamic State's June advance, would be a crucial objective for the Iraqi government and its regional and Western allies in the fight against the insurgents.
WINNING OVER SUNNI TRIBESWinning over Sunni tribes was a central part of the strategy that helped the U.S. military defeat a precursor of Islamic State during the "surge" campaign of 2006-2007. Washington has made clear it hopes the new Iraqi government of Prime Minister Haidar al-Abadi, who took power last month, can repeat it.
Rabia controls the main highway linking Syria to Mosul, the biggest city in northern Iraq, which Islamic State fighters captured in June at the start of a lightning advance through Iraq's Sunni Muslim north that jolted the Middle East.
Twelve Islamic State fighters' bodies lay on the border at the crossing after the battle, said Hemin Hawrami head of the foreign relations department of the Kurdistan Democratic Party, one of the main Iraqi Kurdish parties, on Twitter.
Syrian Kurdish fighters said they had also joined the battle: "We are defending Rabia ... trying to coordinate action with the Peshmerga against Islamic State. It is true," said Saleh Muslim, head of the Syria-based Kurdish Democratic Union Party (PYD).
If Rabia can be held, its recapture is one of the biggest successes since U.S.-led forces started bombing Islamic State targets in Iraq in August.
It is one of two main border crossings between militant-held parts of the two countries, control of which has allowed Islamic State to declare a single Caliphate on both sides. The other main crossing, Albu Kamal on the Euphrates River valley highway, has been a primary target of U.S. strikes on both sides of the frontier this past week.The ability to cross the frontier freely has been a major tactical advantage for Islamic State fighters on both sides. Fighters swept from Syria into northern Iraq in June and returned with heavy weapons seized from fleeing Iraqi government troops, which they have used to expand their territory in Syria.
Washington expanded the campaign to Syria last week in an effort to defeat the fighters who have swept through Sunni areas of both countries, killing prisoners, chasing out Kurds and ordering Shi'ites and non-Muslims to convert or die.
In two complex, multi-sided civil wars, the Sunni fighters are battling against Shi'ite-backed government in both countries, rival Sunni groups in Syria and separate Kurdish forces on either side of the frontier.
Washington hopes the strikes, conducted with help from European allies in Iraq and Arab air forces in Syria, will allow government and Kurdish forces in Iraq, and moderate Sunnis in Syria, to recapture territory.
In Iraq, a coalition of Iraqi army, Shi'ite militia fighters and Kurdish troops known as peshmerga have been slowly recapturing Sunni villages that had been under Islamic State control south of the Kurdish-held oil city of Kirkuk.
"At dawn today, two villages near Daquq, 40 kilometres south of Kirkuk, Peshmerga forces liberated them from Islamic State," an Iraqi security official said.
Islamic State fighters had used positions in the villages to fire mortars at neighbouring Daquq, a town populated mainly by ethnic Turkmen Shi'ite Muslims. When Kurdish fighters entered the villages they were empty, the security official said.
GROUND SHAKING BENEATH OUR FEET Peshmerga secretary-general Jabbar Yawar estimated the Iraqi Kurds had now retaken around half the territory they lost when the militants surged north towards the regional capital Arbil in early August, an advance that helped to prompt the U.S. strikes.
"We have absorbed the shock and are pushing them back," Yawar said. Peshmerga fighters, Iraqi army troops and pro-government militia were advancing north from the Peshmerga-held city of Tuz Khurmatu to drive Islamic State fighters out of the countryside that surrounds Kirkuk, the official said. He credited U.S.-led air strikes with helping the peshmerga clear the two villages.
"This area witnessed intense air strikes from U.S.-led strikes and Iraqi air strikes overnight and at dawn," the official said.
The explosions shook Kirkuk itself: "We felt the ground shaking beneath our feet, and then we heard that there were air strikes outside Kirkuk," said a policeman in the city contacted by Reuters who asked not to be identified.
In addition to aiding the Kurds in the north, U.S. air strikes have targeted fighters west of Baghdad and on its southern outskirts, difficult rural terrain known under U.S. occupation as the "triangle of death".
"We believe the U.S. air strikes have helped in containing Islamic State's momentum," said lawmaker Mowaffak al-Rubaie, a former head of Iraq's advisory security council.
Iraqi officials said U.S. air strikes, along with strikes by Iraq's own aircraft, had killed dozens of Islamic State fighters the previous day south of the capital.
"It appears that 67 (Islamic State) militants were killed in Fadiliya," said an Iraqi security source, referring to a town in the Euphrates valley south of the capital. He said the casualty estimate came from satellite imagery and informants.
The U.S. military said it had conducted 11 air strikes in Syria and the same number in Iraq in the previous 24 hours, describing a range of targets including Islamic State tanks, artillery, checkpoints and buildings.
SIEGE IN SYRIAUnlike in Iraq, where the U.S.-led air strikes are coordinated closely with the government and Kurdish forces, Washington has no powerful allies on the ground in Syria, making its strategy there riskier and more precarious.
The United States and its Western and Arab allies oppose the government of President Bashar al-Assad and are wary of helping him by hurting his enemies. Turkey, the neighbour with the biggest military, has so far held back from joining the U.S.-led coalition, despite an advance in the past 10 days by Islamic State fighters against Kurds near the frontier that has caused the fastest refugee exodus of the three-year civil war.
The fighters have laid siege to Kobani, a Kurdish city on Syria's border with Turkey. The rattle of sporadic gunfire could be heard from across the frontier, and a shell could be seen exploding in olive groves on the western outskirts of town.
A steady stream of people, mostly men, were crossing the border post back into Syria, apparently to help defend the town.
Ocalan Iso, deputy commander of the Kurdish forces defending the town, told Reuters Kurdish troops had battled Islamic State fighters armed with tanks through the night and into Tuesday.
The Syrian Observatory for Human Rights, a body that monitors the war with a network on the ground, said U.S.-led strikes had hit Islamic State positions west of Kobani. Kurdish commanders have complained in recent days that the air strikes hitting other parts of Syria were not helping them at the front.
The Observatory said Islamic State now controls 325 out of 354 villages on the rural outskirts of Kobani.
