Alaa Abu Dhein, a resident of East Jerusalem (the area where Ehud Olmert is planning to give to the Palestinians), murdered eight students (seven of whom were teenagers) of Merkaz Harav yeshiva in Jerusalem yesterday. The following line sums up most of what is needed to understand the situation:
...Abu Dhein was arrested by defense forces four months ago and then released two months later.
Here is the whole article:
The terrorist who killed eight students in a terror attack on Merkaz Harav Yeshiva Thursday night used to work as a driver at the institution, according to his family.
A Zaka man in the Merkaz Harav library works next to an automatic rifle and spent ammunition that was used by the Palestinian terrorist in Thursday night's terror attack.
Defense officials said the attacker came from east Jerusalem, home to Palestinians who hold Israeli ID cards that allow them freedom of movement.
Police would not provide more details Friday, but several residents of the east Jerusalem neighborhood of Jabel Mukaber gave the terrorist's name as Alaa Abu Dhein, 20, and said he had worked as a driver at the yeshiva.
Police later denied that the terrorist had been an employee of the yeshiva.
His family set up a mourning tent Friday and hung green Hamas flags outside their home.
They claimed that Abu Dhein was arrested by defense forces four months ago and then released two months later.
