An Israeli aircraft has fired a missile at a house in a northern Gaza Strip refugee camp, killing at least one person and wounding three others.

Witnesses say the missile destroyed a house in the heart of the Jabalya refugee camp. Hospital workers say a Palestinian man who worked in the camp as a teacher was killed and three women wounded.

It was not immediately clear why the house was targeted. Israeli army officials offered no immediate comment on the incident.

The attack was the latest in a 10-day-old Israeli operation in Jabalya to drive out Palestinian militants who fire rockets into Israel.

Seven Palestinians were killed Saturday following Israeli military operations in Gaza.
