ISIS fighters pounded the Syrian city of Kobani with tanks and heavy artillery Monday as the extremist group came closer to capturing the key city on the border with Turkey.
The fall of the city would carry huge symbolic and strategic weight, giving ISIS sway over an uninterrupted swatch of land between the Turkish border and its self-declared capital in Raqqa, Syria, 100 kilometers (62 miles) away.
Although the fight was not over, CNN crews on Monday spotted what appeared to be the black flag of ISIS flying from a hilltop on the eastern side of the city. The flag was farther east into the city from one shown flying atop a building in video from Reuters and also seen by the CNN crews.
The Turkish military, which has bulked up its defenses along the border in recent days as the fighting has flared, blocked people fleeing the fighting from crossing the border.
