Victoria, TX Vs. Israel

According to this report, the Jews of Victoria, TX are opening up their synagogue to Muslims whose mosque recently burned down:

In the small Gulf Coast city of Victoria, Texas, there are several churches, but just one synagogue, and one mosque - at least, until the mosque mysteriously burned down on Saturday, according to the New York Times.

Now, in a sense, the synagogue has become a mosque: the Jews of Victoria handed the Muslims the key to the building, so they would a place to worship while rebuilding.

“Everyone knows everybody, I know several members of the mosque, and we felt for them,” said Robert Loeb, the president of Bnai Israel, which affiliates with the Reconstructionist movement.

I've been to Victoria. I didn't get the impression people there were bigoted, but there seemed to be a lot of ardent Christians.

I do have two questions about the above report:

• Why does it say the fire was "mysterious"? It's been two days, yet there has been no finding of arson as the cause.
•  Would the people of Israel have done this if the burned down mosque had been in Gaza?
