Explosions at Mosques

There have been a couple of explosions at, or close to Mosques in the last few weeks and the media, particularly the BBC has been very keen to lay the responsibility on "right-wing extremists", the BNP or the EDL, whichever takes their fancy at the time.
How galling it must be for the BBC to have to report that
"Two Ukrainian men have been arrested under the Terrorism Act in connection with explosions in Walsall and Tipton".
Ukraine, along with adjoining countries has a substantial Muslim population, and according to Wikipedia,  the majority of residents in the Small Heath district of Birmingham, where these men were living, are Muslims of South Asian origin.
It might be reasonable to conclude that those arrested are also Muslims and if one wonders why Muslims would attack mosques, one only has to look at Syria, where the fighting is now largely between different sects of the same religion. Could this be the beginning of sectarian battles amongst the Muslims in this country?
Meanwhile I'm not holding my breath waiting for the BBC to apologise to those groups whom they  suggested were most probably responsible for the bombs.
