JERUSALEM, Israel -- The government's Counterterrorism Bureau issued travel warnings for Israelis planning to go abroad for the Passover holiday.

The advisory comes days after three children and a rabbi were gunned down by an al Qaeda-affiliated jihadist at a Jewish day school in Toulouse, France.

The bureau advised Israelis against visiting popular resorts in the Egyptian Sinai and reissued an earlier advisory stating that "terror groups are planning to carry out attacks against Jewish and Israeli sites inside Turkey."

The advisory also noted that Iran and its Lebanese-based proxy, Hezbollah, remained intent on killing and kidnapping Israelis abroad, especially businessmen or government officials.

Among the many countries mentioned in the travel advisory are Jordan, Egypt, Malaysia, Pakistan, Mali, Nigeria, and the Ivory Coast.

Israeli travelers were cautioned against accepting unexpected business offers or gifts and invitations from people they don't know.
