US-led warplanes pummelled jihadists attacking the Syrian town of Kobani on Friday as the Pentagon said there was no imminent threat to Baghdad despite a wave of deadly bombings.
Six strikes hit Islamic State group positions close to the front line in the east of Kobani, taking advantage of new coordination with the town's Kurdish defenders, the Syrian Observatory for Human Rights said.
In neighboring Iraq, sandstorms hampered the US-led air campaign against the jihadists, but despite recent advances west of Baghdad, IS is not poised for an assault on the capital, the Pentagon said.
The dawn strikes in Kobani came after US Central Command said American warplanes struck 14 times around the town on Wednesday and Thursday, including "successful" raids on 19 IS-held buildings.
"There is coordination between the Kurdish forces and the Americans," Observatory director Rami Abdel Rahman told AFP.
"The Kurds are giving them the exact coordinates of where the fighting is."
On Friday, Kurdish fighters faced three attacks by IS militants in the east and near the center, said the Britain-based Observatory, which has a wide network of sources inside Syria.
Previously, Kurdish commanders in Kobani had complained of a lack of coordination with US air commanders to ensure support for their fighters on the ground.
US Engages Syria Kurds
Washington revealed it held its first direct talks last weekend with the main Syrian Kurdish group whose forces have been battling IS.
Earlier contacts with the Kurdish Democratic Union Party (PYD) had all been handled through intermediaries, as the group has close ties with the rebel Kurdistan Workers Party (PKK) — which is on the US terror blacklist — over the border in Turkey.
The PYD has been appealing urgently for weapons to resupply its outgunned fighters in Kobani.
But asked if Washington was discussing the request, State Department spokeswoman Jen Psaki said: "I don't think we're at that point."
The Kurds claimed to have pushed IS back in parts of Kobani as the coalition intensified its airstrikes in recent days.
But the Pentagon warned that the strikes may not prevent the town's fall even though it says several hundred jihadists have been killed.
With the world's press massed just across the border in Turkey, the battle for Kobani has become a high-profile one for both IS and its opponents.
But the jihadists are also fighting on other fronts, both in Syria and in neighboring Iraq.
In eastern Syria, IS lost nine of its fighters in clashes with government forces in the eastern city of Deir Ezzor, the Observatory said.
In Hasakeh province in the northeast, it lost 20 fighters in clashes with Kurdish forces on Thursday.
Coalition forces have now carried out more than 100 airstrikes near Kobani since Sept. 27.
The month-old IS assault on the area has sparked an exodus of some 200,000 mainly Kurdish refugees across the border, where the town's plight has stoked nationalist sentiment among Turkey's own large Kurdish minority.
Ankara's inaction has sparked deadly Kurdish protests that have left at least 34 people dead and complicated Washington's negotiations with its NATO ally for it to play a bigger role against IS.
No 'Imminent' Baghdad Threat
The US military says Kobani may eventually fall but insists it is not a "strategic" location and that other areas carry more importance, particularly in western Iraq and the suburbs of Baghdad.
Bombings in and around Baghdad killed at least 26 people and wounded dozens Thursday, including a double car bombing in the Dolai neighbourhood that was claimed by IS.
Despite such attacks, US military spokesmen Rear Admiral John Kirby said "we don't believe that Baghdad is under imminent threat" from the jihadists.
"It's not the first time in recent weeks or even months that there's been IED (improvised explosive device) attacks inside Baghdad," he said.
"There are not masses of formations of (IS) forces outside of Baghdad about to come in."
Kirby said "terrible" weather had hampered US-led airstrikes in Iraq in recent days.
Iraqi government forces launched an offensive on Friday north of the city of Tikrit, one of a string of mainly Sunni Arab towns north and west of Baghdad that the jihadists seized in June.
President Barack Obama told military chiefs from more than 20 allies this week they were facing a "long-term campaign" to defeat IS, which is well entrenched in a swathe of both Iraq and Syria.
