MOGADISHU, May 26 (AFP) - Rival militias on Wednesday fought in the south-central Somali town of Baidoa, with one side claiming to have killed 30 enemy gunmen after clashes resumed Tuesday, witnesses said by field radio. Battles in and around Baidoa at the weekend between the Mogadishu-based militiamen of warlord Hussein Mohamed Aidid and the local Rahanwein Resistance Army (RRA) resulted in at least 22 deaths, with "dozens" wounded, militia sources said. The fighting erupted after Aidid sent some 45 battle-wagons to Baidoa to protect an incoming shipment of Somali shillings he had printed in Canada. RRA spokesman Mohamed Aden Qalinle told AFP that on Tuesday two rival armed wagons were neutralised after hitting landmines, while two others were destroyed by rocket-propelled grenades. He claimed the RRA fighters had killed at least 30 of Aidid's gunmen on Tuesday, mainly through the use of anti-vehicle landmines, and lost four men themselves, but his figures were impossible to verify, "The RRA also captured a Spanish-made lorry mounted with a ZU-23 Soviet-made anti-aircraft gun and managed to take the weapons from a neutralised wagon which partially survived the blast," Qalinle said. The fighting reignited after Aidid's men made a new attack on RRA militia camps at the nearby village of Eldon. The fighting was continuing on Wednesday, the witnesses said, but no casualties had been reported by midday (0900 GMT). Latest reports said the RRA abandoned the Eldon camps, which are close to the airport. Militia sources in Mogadishu said Aidid faced a setback on Tuesday when his battle commander in Baidoa, Abdulwahan Mohamed, from the Galadle subclan of the Rahanwein, switched his allegiance to the RRA. Aidid's militia commanders in Mogadishu acknowledged the fighting was continuing, but declined to confirm or deny the RRA's casualty figures.
