Turkey says it's unrealistic for it to launch unilateral ground attacks against IS. The US, which is leading an air campaign in Syria, is trying to check the advance of militants against Kurdish forces.
The battle for the Syrian border town of Kobane has pitted Turkey against its NATO allies, which want to see a more robust response to Islamic State's offensive. US-led airstrikes appear to be checking the militants' advance into the town.
If the Syrian border town of Kobane falls, IS will control a long stretch of the Syria-Turkey border, threatening the security of the Kurdish-majority area. US-led airstrikes haven't stopped the advance.
Islamic State forces reportedly have surrounded a Turkish exclave in Syria where the grandfather of the founder of the Ottoman Empire is entombed. Turkey's Parliament is expected Thursday to authorize the deployment of troops to confront IS forces.
Efforts to expand the anti-Islamic State coalition include the debate in Britain's Parliament, deliberations in Denmark and Belgium, and US overtures to Turkey. US and French jets struck IS oil targets overnight in Syria.
Anti-American sentiment is rising in Turkey. Already Erdogan has used state resources to dig into business matters of a US-based Islamist preacher who is a political rival.
