Not in the quantities that American ones do.

Centers for Disease Control and Prevention site above lists that in 2014 (most recent statistical year posted) that 10945 (29 per day) Americans died in gun homicides. That's 3.4 per 100k. There were 15809 homicides in total in 2014.
UK was a little harder to find but one site listed the gun homicides in the UK as 23 in 2013, 12 in 2012, 38 in 2011. That's an average of 24.3 per year.
That's .04, .02 and .06 per 100K.
And total homicides in the UK were: 653 in 2012, 765 in 2011 and 712 in 2010.
(2012 was not listed)
This whole thing shouldn't be about US v UK and/or gun control (the stats really don't reflect well on the US btw and should make you wonder why this is the direction some want to take it). It should be about dealing with terrorists and terrorism. Politicians (and the rest of us in the peanut gallery) can disagree about how to deal with terrorism/terrorists, but using an attack to take shots at another politician/country/city (even if he didn't live in a glass house) and then to also make it about something it isn't really demonstrates everything that's wrong with the lack of leadership being exhibited.
