Local authorities have not ruled out evacuating civilians, while Kiev has demanded a ceasefire.
The OSCE Special Monitoring Mission (SMM) to Ukraine has confirmed that tanks, artillery and missiles are being used around Avdiivka.
Meanwhile, SMM observers reportedly heard more than 400 explosions and many series of machine gun fire over four hours on Sunday night.
