Islamic State militants have captured about one-third of the city of Kobani in the last 24 hours, but Kurdish defenders are fighting fiercely to prevent their advance, Syrian opposition activists said Thursday.

Islamic State forces captured a police station and a secondary school in the eastern part of the city, while fighters from the People’s Protection Units – the Kurdish group known as the YPG, which has controlled the city since the middle of 2012 – were still in control of the city center and the city’s west.

U.S. aircraft launched five airstrikes against Islamic State positions south of Kobani, the military’s Central Command said Thursday. Centcom described the targets as a training camp, a support building, two vehicles and two units of Islamic State fighters, one large and one small. It gave no estimate of casualties, though fighters inside the city said at least 11 Islamic State fighters and six members of the Kurdish militias had died in the fighting.[…]
