BEIRUT,: Syrian rebels dealt a major symbolic blow to the Islamic State group on Sunday by capturing the town of Dabiq where militants had promised an apocalyptic battle.
The defeat for Islamic State came as the United States and Britain warned they were considering imposing sanctions against economic targets in Syria and Russia, which is a key ally of Syrian President Bashar al-Assad, over the government-imposed siege of second city Aleppo.
World powers to try again for Syria ceasefire
The Syrian Observatory for Human Rights, Turkish state media and a rebel faction said opposition fighters backed by Turkish warplanes and artillery seized control of Dabiq. The town, in Syria's northern province of Aleppo, is of little strategic value. But Dabiq holds crucial ideological importance for IS and its followers because of a Sunni prophecy that states it will be the site of an end-of-times battle between Christian forces and Muslims.
US Secretary of Defense Ash Carter said Dabiq's "liberation gives the campaign to deliver ISIL a lasting defeat new momentum in Syria." The Observatory, a Britain-based monitoring group, said rebel forces "captured Dabiq after IS members withdrew from the area".
The Fastaqim Union, an Ankara-backed rebel faction involved in the battle, said Dabiq had fallen "after fierce clashes".
Fastaqim said rebels then went on to seize several nearby towns, including Sawran, Ihtimaylat, and Salihiyah. Turkey's state-run Anadolu news agency said nine rebels were killed and 28 wounded during fighting to capture the towns.
Rebel commander Haitham Ibrahim Afassi told AFP: "I thank God for giving us victory. The heros of the Free Syrian Army have liberated the region." Video footage showed the streets of the town virtually deserted, with black IS flags painted on the facades of buildings as well as extremist graffiti.
Turkey fears Russia-US war over Syria
Dabiq has become a byword among IS supporters for a struggle against the West, with Washington and its allies who are bombing the militants portrayed as modern-day Crusaders. IS, which seized control of large parts of Syria and Iraq in mid-2014 and declared an Islamic "caliphate", has been dealt a series of military defeats this year and is bracing for an assault on its key Iraqi stronghold Mosul. Turkish Foreign Minister Mevlut Cavusoglu said Sunday that Turkish-backed rebels would now focus on taking the militant-held town of Al-Bab in Aleppo province.
Turkey launched an unprecedented operation inside Syria on August 24, helping Syrian rebels to rid its frontier of IS jihadists and Syrian Kurdish militia. President Recep Tayyip Erdogan on Saturday said Turkey would push further south to create a 5,000-square-kilometre (1,900 square-mile) safe zone in Syria.
Clashes took place in Aleppo's northern and southern outskirts on Sunday, as well as in the city centre, the Observatory said. Air strikes on rebel-held eastern areas killed 31 people, including 15 civilians who died in Russian raids, it added.
An AFP correspondent said two buildings had been destroyed and reported nearly non-stop air raids on the opposition-held half of the city since midnight. US Secretary of State John Kerry, in London Sunday for talks on Syria with his British and French counterparts, branded the bombardment of civilians in Aleppo "crimes against humanity".

British Foreign Secretary Boris Johnson warned of possible sanctions. "There are a lot of measures that we're proposing including extra measures on the regime and their supporters," Johnson said. "These things will eventually come to bite the perpetrators of these crimes, and they should think about it now," he warned.
Rebel fire on government-controlled districts of Aleppo left three people dead and more than two dozen wounded, Syrian state news agency SANA said. Fighting has surged in the city following the collapse last month of a ceasefire brokered by the United States and Russia, raising deep international concern.
Kerry was in London to brief Washington's European allies after "brainstorming" talks in Lausanne with the main players in Syria's conflict, but hopes for a breakthrough in the conflict that has killed more than 300,000 people since 2011 remained dim. Saturday's meeting in Lausanne did not produce a concrete plan to restore the truce that collapsed amid bitter recriminations between Washington and Moscow.
Kerry warned Sunday that US President Barack Obama had not taken any option off the table in trying to stop the killing, but downplayed the possibility of increased military action in Syria. "We are discussing every mechanism available to us but I haven't seen a big appetite from anyone in Europe to go to war," he said.
