PATERSON - (AP) - A New Jersey judge has ruled that a pair of twins has different fathers.

Passaic County Judge Sohail Mohammad made the ruling Monday in a paternity case.

It's possible but rare for a woman to give birth to twins with two fathers. Mohammad says he found just two other court cases nationally on such matters.

It can happen when the woman has sexual intercourse with and egg fertilized by two different men.

This instance came to light when a Passaic County woman sought child-support payments from a man she thought was the father her daughters, who were born in January 2013.

Paternity tests showed he was almost certainly the father of one but excluded him as the dad of the other.

The man, identified only "A.S.," owes $28 per week.
