For being.....

[idiotmike]

Dear teachers,

"Iran executed Majid Jamali Fashi, whom it accused of working for Mossad, the Israeli intelligence service, and for being behind the killing of an Iranian nuclear scientist on Israel’s behalf. Iranian state media said that Mr Fashi confessed to the crime."

Above is a paragraph from the Economist magazine, I am not too sure when it mention " for being behind........on Israel's behalf" the use of "for being...." is to describe what can I use "of being...."

Please kindly explain the grammar behind that. Many thanks.

"Of" would be better. He was accused of X, and of being Y.
