First of all, Nginx is already rejecting the request, which is why Nginx
returns a 404.

Locations cannot be based off of the request arguments. You could catch
the request by using something like this (assuming /iclk isn't valid for
some other part of your site):

location ^~ /iclk { return 404; }

In any case, it isn't necessary since Nginx is already doing this for
you.  

If these requests are hacking attempts, you could utilize a tool such as
fail2ban that watched your Nginx logs for requests that match the
pattern and blocked the IP addresses using your system's firewall.

For future reference, if you are going to paste giant sections from log
files, please use pastebin and just provide a link.
