The battle for Kobane has become crucial for both the Islamic State (IS) group and its opponents, with US officials saying Kurdish fighters defending the town look increasingly capable of withstanding the jihadist onslaught.
IS, which declared in June a "caliphate" over territory it seized in Iraq and Syria, was meanwhile described as the world's wealthiest "terror" group, earning $1 million a day from black market oil sales alone.
The Kurds in Kobane have been holding out for more than a month, buoyed by a promise of Iraqi Kurd reinforcements and by US air drops of weapons.
200 Iraqi Kurd peshmerga fighters "I think the Kurdish defenders... are going to be able to hold," a defense official at US Central Command said, speaking on condition of anonymity.
Turkish President Recep Tayyip Erdogan said that 200 Iraqi Kurd peshmerga fighters would travel across his country to join the battle in Kobane, where IS has an estimated 1,000 militants.
On Thursday evening an AFP photographer across the frontier captured on film the moment another apparent strike hit an IS position atop a hill west of Kobane.
A huge fireball dwarfed the few militiamen who had been seen manning the post under the jihadist group's black flag.
The month-old aerial campaign has killed 553 people, all but 32 of them jihadists mostly drawn from overseas, the Syrian Observatory for Human Rights said.
The jihadist toll included 464 IS militants and 57 fighters from the Al-Qaeda affiliated Al-Nusra Front, said the Britain-based Observatory, which relies on a wide network of sources inside Syria.
