The municipalities of Haifa and Hadera have not followed Holon\'s example, and plan to proceed with traditional Purim celebrations, despite security services warnings of impending terrorist attacks. Holon canceled its gala Adloyada celebration yesterday, because of security concerns. Specific terrorism warnings have been received in Haifa. Forces have been beefed up in both cities, especially in Haifa, and all police vacations cancelled. Roadblocks will be set up at several entrances to Haifa.
