Archbishop Desmond Tutu, seeking scholarships for students from his troubled South Africa, said he will return any honorary degrees from U.S. schools that fail to divest their South African holdings within a year.

"I want to give notice here," Tutu said Friday during a speech at Northeastern University, where he was given an honorary doctorate of divinity.The Anglican prelate, who won the Nobel Peace Prize in 1984 for his non-violent opposition to apartheid, said his gesture may be small, but is necessary to preserve his integrity.

Tutu, who received an honorary degree from Harvard in 1979, did not mention Harvard in his speech.
