Ethiopian military forces have crossed back into Somalia, four months after leaving, witnesses told the BBC.
Their reported return comes as Islamist militants continue to seize towns from the fragile Western-backed government.
One resident said he saw Ethiopian troops digging trenches in Kalabeyr, a key junction that links much of Somalia to the Ethiopian border.
An Ethiopian spokesman denied the reports. Its troops left Somalia in January after two years in the country.
When its troops left, Ethiopia made it clear it did still reserve the right to intervene in Somalia if its interests were directly threatened.
