Kampala — The ethnic violence that has erupted in North-eastern Congo has prompted a rethinking in Kampala.

Uganda has supported five factions and attempted to create an umbrella organisation for them as part of its control strategy. However, it is increasingly problematic.

RCD-L (Rally for Congo Democracy-Liberation), which is led by Mbusa Nyamwisi, lost control of Bunia to Hema militia with Ugandan army support.

Besides, RCD-National led by Rogers Lumbala also considers Mbusa Nyamwisi as attempting to undermine it along with the MLC (Movement for Liberation of Congo) led by Jean Pierre Bemba. Lumbala has resolved to uproot Mbusa Nyamwisi from the territory Uganda curved out for him.

This wrangling is responsible for the violence, which is increasingly widespread and has worried UN.

Amos Ngango, the UN secretary general's special representative has already been dispatched to Kampala to ask authorities here to give an account of the Bunia events in which UN has discovered two mass graves.

Besieged by civil war in his own country, Yoweri Museveni, Ugandan president, has ordered the two remaining battalions in Congo to withdraw.

UN entrusted Uganda the responsibility of keeping peace in the region where it has sphere of influence. However, even some of its supported factions, accuse Uganda of not being an honest broker and reportedly siding with one faction against the other.

Mbusa Nyamwisi, whose group was aligned with Lendu community in Bunia, has long been fighting against perceived uprooting from their land by the Hema.

The conflict is further complicating a peace deal that was signed recently in South Africa in which Mbusa was also a signatory in a power sharing deal.

RCD-L has lost ground to Hema militia and is besieged by another faction of Rogers Lumbala-the RCD-Nationale.

Lumbala told journalists in Kampala that his strategy is to uproot Mbusa from his territory, and accused him of plotting with Kinsasha authority to attack MLC, RCD-N positions with help of ex-Rwandese military.

Nevertheless, these developments come amidst renewed moves by the Kinshasa authorities to reach an understanding with her neighbours.DRC has already signed a bilateral peace deal with Rwanda and Kabila has expressed his intention of having the same with Burundi and Uganda.

Apparently, DRC strategy underlines already held view that those countries that supported rebel factions matter more. Besides, Uganda is increasingly suscipicious of factions' moves.

The military and political cooperation treaty between Jean Pierre Bemba and Onusumba raised concern in Ugandan circles. Both Bemba and Mbusa ties with some Mai Mai - who also have ties with Ugandan rebels - is another source of concern.

Lumbala criticised Uganda for helping Mbusa whom he considers unreliable.Wamba Dia Wamba thinks Uganda was mistaken when it created warlords. Commentators say that Ugandan strategy was to avoid dominant groups while increasing political stakes in future government of national unity in DRC.

Nevertheless, there is speculation that business interests are responsible for re-alignment in Bunia, which is a mineral rich area with gold, diamond and oil. In fact, Heritage Oil, which is engaged in oil exploration in Uganda, has extended exploration to this area.
