premise: Israel has blocked a UN human rights fact-finding mission led by South African Nobel laureate Desmond Tutu into the killing of 19 Palestinians in their homes in the Gaza Strip, a United Nations official in Geneva said Monday.
  Israeli authorities will not grant Tutu and his team the necessary travel authorisation, the official added.
  The UN Human Rights Council voted on November 15 to set up the fact-finding mission into the deaths during an Israeli artillery bombardment in Beit Hanun.   The mission was intended to assess the situation of victims, address the needs of survivors, and make recommendations on ways "to protect Palestinian civilians against further Israeli attacks".
  Tutu, the former Anglican Archbishop of Cape Town, chaired the South African Truth and Reconciliation Commission after the end of the apartheid regime.
   What did the end of the apartheid regime allow Desmond Tutu to do?
