The AU Peace and Security Council \"has decided to endorse a harmonised concept of operations for the planned deployment of AFISMA, which is the African-led mission in support of Mali,\" Ramtane Lamamra told reporters. On another note, the UN\'s representative in West Africa met Tuesday with a delegation from Ansar Dine, one of the Islamist groups currently occupying northern Mali, an AFP correspondent said.
