Problem:story: Baghdad, Iraq (CNN) -- As violence continues to wrack Iraq, another ethnic slaughter may be in the making by Sunni extremists from ISIS.

ISIS fighters have besieged the ethnic Turkmen Shiite town of Amerli in the north for two months, and its fewer than 20,000 residents are without power and running out of food, water and medical supplies.

"The situation of the people in Amerli is desperate and demands immediate action to prevent the possible massacre of its citizens," said Nickolay Mladenov, the U.N. secretary-general's special representative for Iraq.

He said the suffering was "unspeakable" and demanded that the Shiite majority Iraqi government "relieve the siege" on Amerli.

Small town fights ISIS

About 5,000 families live in Amerli, which has been under siege for 70 days, according to Dr. Ali Albayati, head of the Turkmen Saving Foundation. He told CNN the town is running without electricity, is out of medicine and can only turn to wells for water.

Nearly three dozen villages surrounding Amerli are already under ISIS control, Albayati said. The people of Amerli are relying on the Iraqi government to take them out by helicopter or support them with food drops, Albayati said. In the past 10 days, he added, only one flight has delivered food.

Surrounded on four sides, the 17,400 residents have had to defend themselves with only the help of local police, said Masrwr Aswad of Iraq's Human Rights Commission.

Their situation echoes the ordeal of Iraq's ethnic Yazidis, whose plight after they were forced to flee into the mountains to escape militants ISIS triggered U.S. aid drops and the first U.S. airstrikes against ISIS. , question: What does he do?
