The pastor at Central Brooks Memorial Church in Karachi, Emanuel Victor, suggested that the message of Christmas was one of peace and love.

U.S. soldier Trent Sutlon acknowledged conditions were different than back home, but insisted that there was still plenty of festive spirit.
"Well, of course the holiday season typically is joyful because you get to spend it with your family and friends," he said "...the situation here is a little bit different, you know, being in the environment that we are in. But even then, there is still a lot of things to look around and be thankful for.
"And the other thing that I think is really interesting out here is seeing all of the different nationalities and how everybody kind of celebrates in their own way with makeshift decorations and it is a really cool environment."
Elsewhere, a spokesman said former U.S. President George H.W. Bush, 88, would be spending Christmas Day in a hospital in Houston, Texas, recovering from a fever and weakness amid a struggle with a bronchitis-like cough.
