How to remove a word from the URL with .htaccess?

I want to redirect http://ift.tt/2e0QBTM to http://ift.tt/2fsZg6E. The blog is built on Anchor CMS and has the following .htaccess file:

Options -indexes

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# Rewrite all other URLs to index.php/URL
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
ErrorDocument 404 index.php
</IfModule>
