A sharp increase in the number of al-Qaida linked fighters joining the fight against President Bashar Assad in Syria is threatening to spill over the borders and prompting the Jewish state to re-evaluate its policy of neutrality in the civil war next door, a senior Israeli intelligence official warned on Friday, Jan. 24, 2014. The official, who spoke on condition of anonymity because military regulations prevent him from releasing the information, claimed more than 30,000 al-Qaida linked fighters are active in Syria, more than double previous Western estimates.
