Americans please take note, Czech Republic is a once-troubled yet entirely peaceful ally tucked into the heart of Central Europe.
Chechnya is a restive Russian region that survived its most recent spate of bloody violence just a decade ago.
It remains a simmering section of the Caucasuses, itself a swirling mix of ethnicities, cultures and language.
Please don’t confuse them, you’re really annoying the Czechs.
As a side note, Twitter users, please verify your information before hitting “tweet.” You have no idea how fast your missives – no matter how well intentioned – can spread misinformation.
To this we offer several tweets lamenting the fact two suspects in the Boston Marathon bombings are from Czech Republic.

He also reaffirmed his country's commitment to fighting terrorism.
Here are some of the offending tweets, and the reactions vis-a-vis this misunderstanding:
