Seven people were wounded early this morning, when gunfire erupted at a party in a residential Brooklyn neighborhood, authorities said.

Shots rang out near Clarendon Road and East 52nd Street in East Flatbush around 12:30 a.m. during a house party gone sour, cops said.

It was not immediately known was sparked the violence but police said that a dispute preceded the gunfire.

A woman, suffering from respiratory failure, was listed in critical condition. Five others were in serious condition, while a seventh person suffered non-life threatening injuries following the disturbance, police said.

“I heard the gun shots — quite a few, 15 at the least. Maybe more,” said an East 52nd Street resident. “I heard people running as soon as the shooting started.”

The victims were rushed to Kings County Hospital, police said.
