Ethiopia warned its citizens today of a possible plot to carry out terrorist acts in the Horn of Africa country.
"The National Intelligence Security Service has received credible information about an impending terrorist plot to be carried out inside Ethiopia," police said in a statement.
They asked car hire firms to scrutinise the identities of their clients and called on the public to tip off police on any suspicious activity.
The Ethiopian government routinely accuses arch-foe Eritrea of backing rebel groups who have bombed civilian targets in the capital Addis Ababa.
The neighbours often trade accusations over their border dispute, in which some 70,000 people were killed.
The two countries have been deadlocked over their 1,000 kms (620-mile) frontier since a 2000 border ruling and analysts fear even a small incident could trigger renewed hostilities.
