Several Killed in Ethiopia Explosion

Three people have been killed in a explosion near Ethiopia's foreign ministry in the capital Addis Ababa, a state-run radio station has reported.
 
It is not immediately clear what caused the explosion at about 7:30 pm (1630 GMT) on Tuesday, but witnesses said that an explosive device may have planted on a minibus.
   
"I was in the area when the blast went off and this minibus was blown to pieces," one eyewitness said.
 
Ethiopian authorities have not provided details on casualties, but witnesses have said that police have sealed off streets leading to the foreign ministry.
   
The explosion comes just over a month after three people were killed and 18 wounded in bomb blasts at petrol stations in Addis Ababa.
