Ethiopian Prime Minister Meles Zenawi on Tuesday accused neighboring Eritrea of supporting rebels to sabotage his country.
Eritrea was supporting former soldiers from the Derg regime, rebels from the Oromo Liberation Front (OLF) and others to sabotage Ethiopia, said Meles, while presenting a report to the 17th regular meeting of the lower House of People's Representatives.
"The wish of the Eritrean government is to see a divided or at least much-weakened Ethiopia. To achieve this goal, it is coordinating and mobilizing remnants of the Derg regime, the OLF and the like," Meles told the lower house of parliament.
Ethiopia and Eritrea fought a 1998-2000 war that killed 70,000 people over their 1,000 km border.
The Ethiopian forces will keep on high alert "to deter the government of Eritrea from initiating armed conflict and to ensure a lasting resolution of the dispute," he warned.
Five separate explosions hit Ethiopia's capital Addis Ababa on Monday, killing one person and injuring at least 14 others.
Up to now, no one has claimed responsibility for the blasts. However, Ethiopian police are suspicious of Eritrea-backed OLF rebels.
The OLF evolved from a political party into an armed movement nine years ago, claiming that the rights of the Oromo people, who make up almost 40 percent of Ethiopia's 70 million, were not being respected.
The OLF are now fighting Prime Minister Meles' government for the independence of the Oromo region from the rest of Ethiopia.
