Around 40 Palestinians were wounded, eight seriously, by an explosion inside a house in the Jabaliya refugee camp in Gaza this morning, Palestinian residents and security sources said.
They said the cause of the blast was unknown, but that it seriously damaged the house of a Palestinian military intelligence official in the camp.
Ambulances rushed the wounded to hospital and Palestinian security officials said they were opening up an investigation into the cause of the blast which damaged about eight houses.
At least two Palestinians were killed while making a bomb in a house in the same area of the refugee camp about two weeks ago, residents said.
