Officials in the Gaza Strip say a series of explosions at the home of a militant commander in the southern part of the Palestinian territory has killed one person Saturday.

Witnesses say a huge explosion, and then a series of secondary blasts, shook the neighborhood of the southern town of Rafah.

It is not immediately clear what caused the blasts and the identity of the victim is still unknown. A spokesman for the radical Popular Resistance Committee, Abu Mujahid, said the blasts originated inside the house of the group's leader, Zuhair al-Qaisi.

The French News Agency quoted Mujahid as saying al-Qaisi was not home at the time of the explosion.
