Ezzedine Al-Qassam Brigades - the armed wing of Islamic Resistance Movement 'Hamas' - announced Wednesday that two of its fighters aka 'Men of Tunnels', including a field commander, were martyred when a tunnel in the Gaza Strip collapsed.

"Field commander Fouad Ashour Abu Atewi, 35, and fighter Ahmad Haidar Al-Zahhar, 23, were martyred Tuesday night during their duty service inside one of the resistance's tunnels," a statement by Qassam Brigades read.

Both martyrs are form Al- Nuseirat refugee camp in the central Gaza Strip, it said.
