Adidas has apologised for sending a marketing email praising customers it said "survived" this year's Boston Marathon.
The subject line of the email sent on Tuesday by Adidas Running read: "Congrats, you survived the Boston Marathon!"
On social media, customers quickly reminded the company about the real survivors of the 2013 Boston Marathon bombing.
Three people were killed and more than 260 were wounded when two bombs exploded near the finish line in that attack.
The sports apparel company quickly apologised, saying it was "incredibly sorry" for the "insensitive" subject line about Monday's race.
