Iraqi Special Forces reached the eastern bank of river Tigris in Mosul on Sunday; it happened for the first time since the US-backed assault on ISIS.
Units of elite counter-terrorism service (CTS) reached fighting their way to a bridge over Tigris that was damaged in the fighting, informed CTS spokesperson, Sabah al-Numan.
It was the first time Iraqi forces reached the river, which bisects Mosul since the offensive was launched to drag out Islamic State in October. The forces had only penetrated the eastern parts of Mosul so far. The city is Islamic State's last major stronghold.
"This morning CTS troops advanced in two directions towards the Baladiyat and Sukkur districts," Lt General Abdelwahab al-Saadi said.
"During the advance, Daesh [ISIS] tried to confront us from the historic hill," he said, perhaps referring to the hill near the ruins of the ancient Assyrian city of Nineveh.
