"What has just happened with the attempted harassment of sixth graders should be a wake-up call for all of us," says French Education Minister Jean-Michel Blanquer. Blanquer on Friday urged teachers to be vigilant after a bizarre cyber-harassment campaign erupted among school students targeting those born in 2010. The viral hashtag #anti2010 has alarmed parents because it involves 10- and 11-year-olds in sixth grade -- which marks the all-important entry into secondary school. SOUNDBITES
