The United States and its allies have staged 30 air strikes on Islamic State militants in Syria and Iraq over the past 72 hours.
The U.S. Central Command said on November 21 that 23 of the strikes took place in Iraq, including six near Baiji against Islamic State buildings, vehicles, and tactical units.
Another six of the strikes were near Kobani, Syria, where besieged Syrian Kurdish fighters are battling Islamic State militants.
Separately, Islamic State militants have launched a new offensive in Ramadi, the capital of Iraq's western Anbar Province.
Security officials said the group's fighters pounded Ramadi’s center with mortar rounds on November 21, while clashes broke out around the city.
Parts of Ramadi, 100 kilometers west of Baghdad, are already held by Islamic State militants who control large parts of northern and western Iraq.
