For years, Senegal's political leaders have struggled to end an age-old phenomenon, known locally as 'Talibe'. It is a practice where young boys, sent to religious leaders for instruction, are in turn sent back out onto the streets to beg for money to pay for their religious education. The country's president, Macky Sall has promised to ban the practice, and so have his predecessors, but to no avail. Rights activists in the West African nation say the President's inability to halt the practice is out of fear of incurring the wrath of the religious leaders who back the practice. And, Nigerian authorities dispute UN data suggesting over 20 million children are out of school.
