A car carrying Hamas militants exploded in the Gaza Strip today, causing several casualties.
Hamas said it believed the blast was caused by a roadside bomb. Tensions remain high in Gaza between Hamas and other armed Palestinian groups four months after Islamists took control of the territory.
An Israeli army spokeswoman said Israel was not involved in the attack.
Medical workers said three Hamas security personnel were wounded in the explosion on a coastal road in central Gaza.
Hamas has in the past accused members of Palestinian President Mahmoud Abbas's Fatah faction of carrying out attacks against its security forces.
Hamas has clashed recently with clan members associated with Fatah as well as the Islamic Jihad militant group.
