(KUNA) -- Israel will enforce a comprehensive blockade on the West Bank and Gaza Strip upon the directions of Defense Minister Amir Peretz, the Israeli radio reported Thursday. Peretz's decision came after Israeli security agencies were tipped that the Palestinian resistance intended to carry out operations inside Israeli towns. The siege was also in light of the deteriorating security situation in northern Israel.The Israeli police announced yesterday that it arrested a Palestinian who they claimed was on his way to blow himself up in Tel Aviv. Israel raised its alert level to the maximum and its security forces posted many military checkpoints after it received several warnings on the probability of Palestinian suicide operations in Israel.
