LASTEST NEW: Yemen agrees new ceasefire after Ibb fighting

Sunni tribesmen and Shia Houthis sign pact to end violence in central province, where earlier clashes killed 20 people.

Tribesmen and Shia Houthi fighters have signed an agreement that should end hostilities in Yemen's Ibb province, after renewed fighting breached a day-long ceasefire pact. The second ceasefire, which was signed on Saturday, states as a condition the safe withdrawal of all Houthi fighters from Ibb. A 24-hour ceasefire agreement between the warring sides was reached on Friday, interrupted by the death of at least 20 people in fighting on Saturday. Violence erupted when tribesmen set up a checkpoint in Yareem town to prevent the Houthis from entering the provincial capital of Ibb. for the government to evacuate its soldiers and civil servants by November 30. Al Jazeera's Omar Al Saleh, reporting from Sanaa, said that due to the rebels making new gains every day and the secessionist movement in the south, there was "utter chaos in every corner of the country". "Many Yemenis are now worried that there could be a sectarian war in the north and a secessionist war in the south," Al Saleh said. "The secessionists in the south are now taking advantage of the chaos in the north and they are demanding self-determination and full independence of the south of Yemen." The Houthis, who hail from the northern highlands and champion the interests of the Zaidi community which make up one fifth of Yemen's 25 million population, are increasingly imposing their authority outside the capital as well as in it. The group wants the northern part of the country to be one region instead of three and are also seeking a bigger say in drafting the constitution.
