Terrorism training went awry on Friday morning, as an accidental explosion at one of Hamas's Gaza terror bases left four clumsy terrorists injured.
The explosion occurred at a training camp in Khan Younis, in the south of Gaza.
Hamas's Ministry of Healthy spokesperson Ashraf al-Qidra told Arab Ma'an News Agency that the four were taken to local hospitals for treatment.
Al-Qidra described their wounds as ranging between "moderate and dangerous."
The blast is not the first "work accident" by bumbling Gaza-based terrorists.
Two other Islamic Jihad terrorists died two days earlier in an explosion that reportedly occurred while training with various devices.
Likewise, a Hamas terrorist was killed by an explosion in early March which wounded nine others, in a blast that "occurred during a training session in bomb-making," according to a spokesperson of Hamas's military branch.
Such "work accidents" are not limited to Gaza; in March a Sinai-based terrorist group acknowledged that one of its founders, who took part in the 2011 coordinated attack on Eilat that killed eight Israelis, died. The terrorist was involved in a car crash, which detonated the explosives he was transporting.
