FILE - In this Friday, July 20, 2012 file photo, family and friends attend the funeral of Itzik Kolengi, 28, who was killed and his wife injured in a suicide bombing in Bulgaria Wednesday in Petah Tikva, Israel. Israel's prime minister said Sunday, July 22, 2012 that his country is on alert for plots to kill more of its citizens overseas, after speculation that last week's deadly bombing of a tour bus in Bulgaria was a rehearsal for a spectacular attack on Israel's Olympics team.
