JUBA
Ugandan President Yoweri Museveni said Monday that he was prepared to send Ugandan troops to South Sudan to fight "rebels" there.
Speaking to reporters in Juba, Museveni reiterated his country's support for South Sudanese President Salva Kiir.
"We gave [sacked South Sudanese vice-president] Riek Machar four days to respond [to the ceasefire offer]," he said.
"And if he doesn't, we shall have to go for him, all of us," Museveni added. "That is what we agreed in Nairobi."
He went on to say that Kampala was ready to send troops to South Sudan to fight Machar's "rebels."
South Sudan has been shaken by violence since mid-December, when Kiir accused Machar of standing behind a failed coup attempt.
A subsequent government crackdown landed many of Machar's supporters in jail, but the former VP managed to flee to South Sudan's Jonglei State, a stronghold of his Nuer tribe.
Although Machar had earlier denied involvement in the alleged coup, his forces have reportedly since captured parts of the country's Jonglei and Unity states.
