The town of Marka in southern Somalia is known for being a rebel stronghold that was solidly under the control of al-Shabab.
But two weeks ago, the armed Islamist group fled, abandoning the town almost without a fight. Still, the risk of ambush remains high.
The African Union, which has a heavy troop presence in the area, says al-Shabab might have pulled back but they have not gone away.
Al Jazeera's Peter Greste reports from Marka.
