LAGOS, Oct. 31 (Xinhua) -- Jean Ping, the chairman of the Commission of the African Union (AU), is warning that the crisis in Guinea is in a very dangerous situation.

Ping issued the warning on Friday in the Nigerian capital Abuja at a dinner hosted by Nigeria's Foreign Minister Ojo Maduekwe, noting that the rest of the world is looking forward to how the AU will take measures to resolve the Guinean crisis.

"The situation in Guinea is very unsafe," the News Agency of Nigeria quoted him as saying.

He said the AU had adopted many resolutions on Guinea before the killing of more than 120 demonstrators by Guinean soldiers.

"The AU had given an ultimatum to the Capt. Dadi Camara-led military junta to go back to their previous commitment; otherwise sanctions will be imposed on them," he said.

"The ultimatum ended on Oct. 17, the exact day the Economic Community of West African States (ECOWAS) took its decision on Guinea," he added.

Ping, who lauded the West African bloc ECOWAS for its decision on Guinea, stressed that the AU must give a strong support to ECOWAS.

"This will show the rest of the world that we (AU) are not compromising a situation where women were raped and innocent people killed," he said.

"It is not acceptable to present that type of image of Africa to the rest of the world," he added.

Ping, a Gabonese diplomat and politician, was elected into office on April 28, 2008.
