South Sudan government agrees in principle to cease-fire From Mading Ngor, for CNN December 27, 2013 -- Updated 1623 GMT (0023 HKT) South Sudan government now awaiting rebels' response, official says Deal reached during meeting of regional leaders in Kenya Fighting has forced more than 121,000 people from their homes, United Nations says Juba, South Sudan (CNN) -- South Sudan's government says it has agreed "in principle" to a cease-fire meant to stop fighting that has left more than 1,000 people dead and forced more than 121,000 from their homes. Rebel leaders have yet to respond to the proposal, Information Minister Michael Makuei Lueth told CNN, leaving it unclear Friday what immediate impact the agreement would have on the fighting. The deal was reached Friday during a meeting of regional leaders in Nairobi, Kenya. Details of the cease-fire proposal were not immediately available, but Leith said President Salva Kiir's government is open to "unconditional dialogue" to end the violence. "We are now awaiting a response from the rebel leader Riek Machar," Leith added. Meanwhile, U.N. officials and aid workers struggled to protect and provide food, shelter and medical care to those who have fled the fighting, which has spread to seven of South Sudan's 10 states, according to the United Nations. More than 63,000 people have crowded on to U.N. bases in South Sudan seeking shelter from the violence, requiring a massive influx of aid. U.N. workers on Friday were able to resupply a U.N.-operated hospital in Malakal, U.N. Assistant Secretary-General Toby Lanzer said on Twitter. The U.N. Humanitarian Air Service also began flying in aid workers and supplies, he said. Tensions in the world's newest country broke into open fighting on December 15, pitting Kiir's government against supporters of Machar, Kiir's former vice president. Kiir and Machar are longtime rivals from two different tribal clans -- Kiir is from the Dinka tribe, Machar from the Neur. Kiir dismissed Machar earlier this year and accused him of attempting a coup when the most recent fighting broke out.
