The Democratic Republic of Congo (DRC) president wants to urgently end talks with rebels in the country's east, Ugandan and Congolese statements have said, despite no deal was reached.

DRC President Joseph Kabila and Uganda's Yoweri Museveni met on Monday in Uganda's capital to discuss the deal, but there was no sign of a breakthrough on the wording of the accord that scupper a signing last month over the DRC's M23 rebels.

"The two presidents agreed that the Kampala dialogue between the government of the DRC and M23 should be brought to a conclusion as soon as possible,"  said DRC in a written statement on Tuesday.

The Ugandan announcement repeated the message, with minor variations in the text but did not say what a final deal should look like.

Kinshasa and the M23 rebels failed to seal an agreement last month after squabbles over what it should be called.

According to the source, however, the insurgents were ready to sign a peace agreement but the DRC wanted to call it a declaration that reflected the rebels' military defeat.
