In a statement, the organization said that "in light of the escalation by the enemy and in light of the ugly crime in Rafah, the Palestinian resistance won't sit with its arms folded and the enemy will pay a price for its crimes. The coming days will prove our warnings and the enemy must wait and see this."
The military wing's stance was strengthened by the Palestinian National Interior Minister, Khaled Abu Hilal, who said that "it is the right of the Palestinian resistance groups to hold weapons and training facilities in order to deal with the occupation," at a Gaza press conference.
"The government will do everything to differentiate between resistance weapons and illegal weapons," he said.
The Hamas military wing has broke its long silence, held since the Palestinian elections, following criticism leveled at it and other organizations, and since Hamas has risen to power, it has refrained from taking an active part in attacking Israel.
The Salah al-Din Brigades, whose members were killed yesterday, are thought to be closest to Hamas – and the two organizations share political and physical activities.
Earlier, Fatah's al-Aqsa Martyrs Brigades and the al-Quds Brigades of the Islamic Jihad, as well as the Salah al-Din Brigades of the Popular Resistance Committee threatened an unprecedented response against Israel.
Meanwhile, Hamas spokesmen and ministers in the government rejected reports in the press that the organization is ready to adopt a political solution based on two states living side by side.
Both Palestinian Prime Minister Ismail Haniyeh and his deputy Dr. Nasser al-Shaar denied the reports.
On Saturday morning, Haniyeh said that the Palestinian government had no plan to change its stance in light of the cessation of aid on the part of the U.S. and the EU.
