Originally the PRC had stated they would not adhere to the cease-fire but after a few parting shots they seem to have changed their mind. From their website:
It is important that Westerners see the actual words that these people speak publicly. By the time it gets to the Western media the above statement, if mentioned at all, becomes "The Popular Resistance Committees military wing announced Monday they would adhere to the ceasefire." The seething hate always gets cut out, and over time well-meaning (and not so well-meaning) leftists start to believe that these people are reasonable and can be persuaded to eventually accept Israel's existence.
The Nasser Saladin Brigades Mujahid was able by the grace of Allah Almighty to pound Zionist occupation settlements with rockets that have killed and wounded dozens of Zionists, and which also led to the creation of a state of terror and paralysis of the movement in the south of occupied Palestine that continues.
The military spokesman for Al-Nasser Salah al-Din Brigades said the Brigades announced a temporary halt in rocket fire for the interest of the Palestinian people.
But isn't it great that the spokesperson for the group talks about how brave they are but refuses to show his face?
