Iraqi Kurdish fighters have joined the fight against Islamic State militants in Kobani, hoping their support for fellow Kurds backed by U.S.-led air strikes will keep the ultra-hardline group from seizing the Syrian border town.
The Syrian Observatory for Human Rights, which monitors the civil war, said heavy clashes erupted in Kobani and that both sides had suffered casualties, while the U.S. military said it had launched more air raids on Islamic State over the weekend.
