Peter is completely correct, however in this sentence I feel like the author is also trying to emphasis the seriousness through repetition – because usually it would be unnecessary to say both. If there are charges, there should already be accusations. Hard to know without reading it myself, but just a thought.

They have similar meaning however a "charge" is a formal legal term for an accusation of a crime and the first step in the process of bringing the person to court. where he or she will asked to plead guilty or not guilty to the charge.. "After his employer accused him of stealing the company's money, the Police investigated and ultimately charged him with stealing/theft".
