Baidoa — The spokesman of Al-Shabaab Islamist movement, Mukhtar Robow Ali (Abu Mansoor), denied Thursday that his group is negotiating with the newly elected Somali president Sheik Sharif Sheik Ahmed and his government.

The spokesman held a press conference in Baidoa, the former seat of the Somali transitional parliament, and told reporters that his movement will rule Baidoa under Islamic Sharia law.

Al-Shabaab seized Baidoa last month after the Ethiopian troops pulled from it.

"We are not going to him and we will not meet him forever," Abu Mansoor said.

"We warn Nigeria against sending its troops to our soil, we will fight with your soldiers," Abu Mansoor added.

He vowed that they will continue the fighting against foreign troops and what he described as an "apostate" government until the country is ruled under the Sharia law.

Somalia's president Sheik Sharif Sheik Ahmed said Tuesday that he met with some opposition leaders although he did not specify the members he met.
