MURSITPINAR, Turkey — The U.S.-led coalition intensified its aerial bombardment of Islamic State positions Thursday in the Syrian border town of Kobani as the extremist group fought street battles with Kurdish forces and reportedly rushed in reinforcements.
The battle for the town near the frontier with Turkey has emerged as a major early test for the air campaign aimed at rolling back and eventually destroying the extremist group.
It has also strained ties between Washington and Ankara over the long-term U.S. strategy in Syria. On Thursday, the U.S. special envoy for the coalition, retired Marine Gen. John Allen, and NATO chief Jens Stoltenberg were in Turkey to press the country to join military operations.
Turkish officials have said that while they do not want Kobani to fall, they will not take on a greater role until the coalition outlines a broader strategy that also includes attacking Syrian President Bashar Assad, who is best positioned to benefit from any rollback of the Islamic State group.
But attacking Assad's regime "is not the focus of our international coalition and not the focus of our efforts by the United States," State Department spokeswoman Jen Psaki said.
Psaki said Allen and Turkish officials discussed ways to advance the effort against the Islamic State group and said a joint military planning team will visit Ankara early next week.
"Both sides also agreed that we will continue a dynamic and deepening bilateral consultation process across the multiple lines of effort against ISIL, including military support, countering foreign fighters, counter-finance, humanitarian assistance, and de-legitimizing ISIL's messaging and rhetoric," she said using and acronym for the Islamic State group.
Turkey also has called for the creation of a buffer zone inside Syria to secure the border, but the White House and Pentagon said Wednesday the U.S. is not considering that option. Such a zone would be costly and complex to enforce.
