Yishai: Escalation requires us to take action

Interior Minister Eli Yishai called for Israel to act after the bombing in Jerusalem and the rocket attacks in the south on Wednesday.
"I see the escalation is already here in a number of fronts - in the south and also in Jerusalem," Yishai said, while visiting the scene of the explosion.
He added that  "recent events require us to take action. If we don't do this we will lose our power of deterrence."
