Two Palestinian militants were killed and two others were injured Saturday in an explosion at a military training site in the southern Gaza Strip, an official said.
Ashraf al-Qidra, Gaza's health ministry spokesman, said two "unidentified citizens" were killed and two sustained serious injuries in an explosion in Khan Younis, without providing details about the cause of the explosion.
Islamic Jihad said in a statement that the men who died were affiliated to the faction's military wing, the al-Quds Brigades.
Islamic Jihad identified them as Ahmad Haidar Vhjan, 28, and Abdul Salam Yusuf Dahlan, 27.I count 20 Palestinian Arabs killed by "work accidents" and rockets that have fallen short in 2014.
Perhaps one of the international organizations that the PLO had joined will be able to give advice on workplace safety for terrorists.
