Forces in support of Cote d'Ivoire's presidency claimant Alassane Ouattara on Tuesday declared control of two more towns after taking a strategic town the previous day.
The Republican Forces backing Ouattara conquered Daloa in the west and Bondoukou in the east of the West African country after an overnight fight.
Eyewitnesses interviewed by Xinhua said they had heard heavy gunshots in several parts of Daloa on Monday night.
"Since morning, rumours of an attack by 'rebels' were spreading around. When we heard loud gunshots this evening, we knew that they had arrived," a resident of the town said.
He said most of the town's dwellers were hiding in their homes.
The newly announced gain followed the fall of the western town of Duekoue on Monday from the country's incumbent leader Laurent Gbagbo.
Duekoue is the gateway to almost all of regions under Gbagbo's control, especially to the political capital Yamoussoukro and to the town of San Pedro, which has the main port for exporting the country's cocoa.
Duekoue is the sixth locality to be conquered by pro-Ouattara forces since February after Zouan-Hounien, Bin-Houye, Toulepleu, Doke and Blolequin.
An all-out war is apparently unfolding in the country amid the military advances of the Republican Forces composed of the ex-rebel New Forces (FN) and soldiers defecting from Gbagbo's regular army.
Gbagbo vows to hold on power in defiance of the international recognition of Ouattara as the president-elect after the Nov. 28 run-off.
The standoff has sparked fears of a repetition of the 2002-2003 civil war, which divided Cote d'Ivoire into the FN-controlled north and Gbagbo's south.
