US Central Command said in a statement on Wednesday said at least one strike hit a Syrian area northwest of the Iraqi border. Activists said more strikes hit the Kurdish-dominated Syrian town of Kobani, an area that have been besieged by IS fighters for past week.
Tens of thousands of residents have been fleeing the IS assault on the town over the past few days. But as Al Jazeera's Stefanie Dekker reported from the Syrian-Turkish border, many residents were returning to Kobani on Wednesday upon hearing the reports of the strikes on IS.
"A lot of the Kurds who are going back to Syria are young men who want to take the matter in their own hand and fight the IS on their land," she said.
Turkey said neither its air force nor the US airbase in southern Turkey had been used, according to Dekker. So far, 20 air strikes have been launched across Syria over the past two days, Central Command said.
The strikes in Syria were carried out on Tuesday overnight with help of five Arab nations, namely Saudi Arabia, United Arab Emirates, Qatar, Bahrain and Jordan. The US-led campaign opens a new front in Syria and thrusts Washington into the country's three-year-old conflict. The US has launched nearly 200 strikes in Iraq in recent weeks against IS fighters, who have captured large swathes of land in Iraq and Syria over the past few months.
On Wednesday, the US military said it launched three strikes on the IS in Iraq. One hit west of Baghdad and two others struck southeast of Irbil.
