N'DJAMENA, March 22 (Reuters) - Chad said on Thursday that warplanes from neighbouring Sudan have bombarded two towns in the violence-plagued east of the country, killing several people and violating a non-aggression pact signed last month.

"The Chadian government reserves the right to use all available means to assure the defence of its territory," read a communique signed by government spokesman Hourmadji Moussa Doumgor.
