Islamic State fighters have launched simultaneous attacks against Syrian government and Kurdish militia forces, moving back onto the offensive after losing ground in recent days to Kurdish-led forces near the capital of their caliphate.
Islamic State sought to retake the initiative with incursions into the Kurdish-held town of Kobani at the Turkish border and government-held areas of Hasaka city in the northeast.
In a separate offensive in the multisided Syrian civil war, an alliance of rebels in the south of the country also launched an attack with the aim of driving government forces from the city of Deraa.
