Video posted online Saturday allegedly shows a brigade aligned with the Free Syrian Army claiming to have taken control of parts of the Syrian border town of Kobane, the focal point of the U.S.-led coalition against targeting the Islamic State of Iraq and Syria (ISIS).
The video allegedly shows members of the “Northern Sun Battalion” of the “1st Dawn Brigade,” an FSA group, inside the industrial sector of the town that borders Turkey.
Fighting intensified Saturday in the besieged Kurdish town as U.S.-led coalition jets struck suspected ISIS targets there.
U.S.-led coalition warplanes pounded suspected ISIS targets at least six times in Kobane after the fiercest shelling in days by the militants shook the town's center and hit border areas within Turkey, Reuters news agency reported.
Shelling continued after the strikes hit the center of Kobane. Several mortars fell inside Turkey near the border gate, called Mursitpinar, Reuters quoted witnesses as saying.
ISIS militants have battled Kurdish fighters for a month to take control of Kobane and consolidate a 95 km stretch of land they control along the Turkish border, but stepped-up air strikes in recent days have helped Kurds fend off the advance.
The coalition has been bombing ISIS targets in Iraq since August and extended the campaign to Syria in September after ISIS, a group that espouses a rigid interpretation of Islam and initially focused on fighting Syrian President Bashar al-Assad's forces, made huge territorial gains.
NATO member Turkey is a somewhat reluctant member of the coalition, insisting it must also confront Assad to end a civil war that has killed some 200,000 civilians since March 2011.
On Saturday, the Britain-based Syrian Observatory for Human Rights said U.S-led forces bombing Islamic State in Syria killed 10 civilians in two separate air strikes.
But U.S. Central Command said there was no evidence to back up the report. Its forces use mitigation measures to reduce the potential for civilian casualties, a spokesman said.
Reuters said it cannot independently confirm the reports due to security restrictions.
In Kobane, a commander for the YPG, the Syrian Kurdish militia defending Kobane, who would only gave her code name Dicle, said ISIS’ renewed attacks were aimed at severing the town's last link with Turkey.
"They want to cut off Kobane's connection with the rest of the world," she told Reuters by telephone. "Turkey is not allowing in fighters or weapons, but they send aid at Mursitpinar. The Islamic State wants to destroy this gate so that we will be completely trapped here."
Turkey has refused to rearm beleaguered Kurdish fighters, who complain they are at huge disadvantage in the face of ISIS’ weaponry, many of it seized from the Iraqi military when it took the city of Mosul in June.
Turkey views the YPG with suspicion for its long-standing links with the Kurdistan Workers Party (PKK), which has waged a 30-year armed campaign for self-rule in Turkey.
President Tayyip Erdogan said earlier this month the PKK was no better than the Islamic State in his view.
This stance sparked outrage among Turkey's own Kurds, who make up about 20 percent of the population. Riots in several cities earlier this month killed more than 35 people.
The Syrian Observatory said the Islamic State had launched at least 21 mortar attacks on Saturday close to the border.
Abdulrahman Gok, a journalist inside Kobane, said by telephone said the fighting was the worst in two days. "In the past hour, the shelling has intensified. They are firing almost one every two minutes," he said, adding that the insurgents were aiming at the east side of town towards the Mursitpinar gate.
A cloud of black smoke towered over the center of Kobane following the latest air strike as the roar of fighter jets could be heard from a blue sky. Gunfire popped in the west and centre of town.
Elsewhere in Syria, government forces shelled neighborhoods in Damascus, the southern province of Deraa and the central province of Homs, opposition activists said.
Army helicopters were dropping improvised barrel bombs on the town of Khan Sheikhoun, in northwest Idlib province, which also borders Turkey, they said.
ISIS supporters circulated what they said was a nine-second video clip of a fighter jet said to be flown by ISIS militants.
The Observatory reported that Iraqi pilots who have joined Islamic State in Syria were training members of the group to fly in three captured fighter jets over the captured al-Jarrah military airport east of Aleppo.
U.S. Central Command said on Friday that it was not aware of ISIS flying jets in Syria. Reuters could not confirm the authenticity of the footage, which showed a jet flying at low altitude.
