This seems clearly to be an anti-Western attack, based upon the locations hit and the descriptions of the victims at the moment. Not good.
On a personal note, it is ironic that one of the hotels hit is the Taj. I was there back in 1993. Along the side of the right-side of the hotel along the street there was a shanty town built up along the sidewalk. I remember a kid running up to me with his hands out asking for US dollars. I only had large bills with me, so I reached into my pocket to give him change. The kid gave me a dirty look, took the few coins, and ran off. hahaha . . . I'll always remember that.
EDIT: From back in 2006, an old post about Bombay (Mumbai) and the Taj...
Bombay (before reverting back to Mumbai) - This was a very very busy city, with buildings stacked on top of each other for blocks. Unfortunately, it was also a very dirty city, with the bay in which we were anchored had floating trash and dead animals in it. It was a quick reminder that, no matter how advanced they are, India was still a borderline third-world nation. If that wasn't enough, in the city there is a grand hotel called the Taj Mahal, complete with a British butcher standing in front of it to open the door for you. Along the side of the hotel (which ran the length of the street) were little shanties built up with homeless begging the tourists for American dollars. It was a sad sight. Traffic was also a nightmare. In what most of us would consider a three-laned road, they were able to fit 5 lanes of traffic travelling at rediculous speeds . . . and no cross walks. Ugh . . . I was more than glad to go back to the ship.
