Sacked South Sudan Vice President Riek Machar has been spotted in Dodoma, Tanzania where he is allegedly seeking refuge. A highly placed source told The Star that embattled Machar gained entry into Tanzania four days ago, and later was later spotted on Satellite. The alleged presence of Machar in Tanzania coincides with the urgent visit of Cord leader Raila Odinga into the country. Odinga, who was scheduled to preside over a function in Kisumu town on Saturday, hurriedly left for a meeting in Tanzania on Friday evening. A reliable source said the main agenda of the meeting held last night and today (Saturday) and attended by senior leaders from various countries was to dicuss Machar's presence in Dodoma. The source who sought anonymity said more inner details of the meeting, where a Head of State was present, are still unclear since it was highly secretive. According to the source, Machar’s presence in the country was deliberated during the meeting also attended by the vice president from a neighboring country. The former vice president returned to the capital Juba in April after a peace deal, but left again last month when new clashes broke out. President Salva Kiir sacked Machar and replaced him with Taban Deng Gai, his former ally after he failed to honour ultimatum to return to Capital Juba. Machar, dubbed 'prophet of doom' by president Kiir has never made any statement since he was replaced as vice president with Gai, according to the source. Machar, the previous vice president, and the SPLM-IO group he leads, have been caught up with more than two years of on-and-off, ethnically charged fighting with supporters of the country's President Kiir. Members of the SPLM-IO loyal to Machar accused Kiir of stockpiling weapons, including surface-to-air missile batteries, around Juba in "a serious and direct threat to the national security". However, government military spokesman Lul Ruai Koang declined to comment on the detail of the accusation but said the army was authorised "to strengthen our air defence capability and to defend the territorial integrity of this country". The alleged entry of Machar in Tanzania comes as the UN Security Council on Friday authorised the deployment of a 4,000-strong protection force in South Sudan's capital, Juba. The authorization is part of the U.N. peacekeeping mission and threatened an arms embargo if the government does not cooperate. The U.S.-drafted resolution was adopted with 11 votes in favor. Russia, China, Egypt and Venezuela abstained. This follows several days of heavy fighting involving tanks and helicopters in Juba last month between troops loyal Kiir and those backing former Machar that raised fears of a return to full-scale civil war in the world's newest nation.
