At least 20 killed in blasts

At least 20 people were killed on Monday in series of blasts at several locations linked to Chad's police in the capital, N'Djamena, security sources told Reuters.

One international security source said seven people were killed in an initial suicide attack and another 35 people died when explosives planted at the police training school went off. A second source said at least 20 people had been killed but did not give a breakdown of the incidents.

The interior minister confirmed at least one suicide attack but gave no further details.
