The government, which has been conducting airstrikes, had earlier claimed it had "made gains" in the battle, but has yet to fully retake the city.
Senior military officials told reporters that they believed the militants were hiding in an extensive network of underground shelters, built years ago.
"There are underground tunnels and basements that even a 500-pounder (bomb) cannot destroy," said Maj Gen Carlito Galvez, head of the military command in the Western Mindanao region.
Government and military estimates on the number of militants left in Marawi have ranged from 40 to 200.
The militants were also apparently well-prepared for a possible siege, and had placed supplies in mosques and religious schools - which are off-limits for air strikes - days before seizing the city, said officials.
Military spokesman Lieutenant-Colonel Jo-ar Herrera told AFP news agency that these buildings contained at least a month's worth of food, as well as weapons such as machine guns.
The fighters, from the Maute group linked to the so-called Islamic State, invaded the city shortly after an attempt by the Philippine military to capture top militant Isnilon Hapilon.
Among those fighting in Marawi include citizens of Indonesia, Malaysia, India, Saudi Arabia, Chechnya and Morocco, according to Reuters news agency.
