This is not news - previous rabbis have ruled the same way.
However, interesting to note that Jews aren't allowed to even step inside a Christian Church - let alone pray in one:
I'm sure this news will cause the 'usual crowd' much frustration - for they wish to believe that Jews and Muslims really can't get along and that Christians are the true friends of Jews. But reality and loon hype are rarely on speaking terms.
