I have posted yesterday about the bomb under the car of the Palestinian professor `Abdus-Sattar Qasim. Here is a picture of the car (thanks to M. for taking it). I have the permission of Qasim to say that he suspects Dahlan gangs and that this is the fourth time his car was bombed and was once shot at.
PS M sent me this clarification: "just for clarification: 4th time he was attacked, 2nd time his car was attacked, and 1 of those attacks he was not shot at, he was shot."
