A trickle of information about the supposed Tanzim ceasefire here.

A European diplomat (elsewhere described as British) and a "peace worker" had been making rounds among militia leaders and were convinced that the militias were ready to declare a ceasefire. Meanwhile Mohammed Dahlan and associates were trying to do something similar but without success. I'm still skeptical.

According to the diplomat, the ceasefire declaration was going to be signed by Fatah's secretary-general Hussein al-Sheikh. al-Sheikh was interviewed on Israeli radio a few weeks ago and you can read a transcript here.
