GAZA, April 17 (Xinhua) -- The armed wing of Hamas al-Qassam Brigades said that one of the group's militants was killed overnight Monday in a tunnel collapse in eastern Gaza.
Medical sources at Shifa Hospital in Gaza City confirmed the militant's death. The sources said three others were injured.
Hamas uses tunnels underneath Gaza as a strategic weapon either to store arms, to hide during wars or to carry out attacks using the tunnels into Israel.
Over the past three years, more than 20 militants died in the same circumstances, according to Gaza rights groups.
