At least seven countries have issued safety warning to the citizens who intend to visit the US over the several instances of gun violence and mass shootings in the country.

New Zealand, Canada, Australia, the United Kingdom, France, Venezuela, and Uruguay have each urged precaution for travelers when visiting the US, due in large part to gun violence.

In the first weekend of May, eight people were shot and killed at a busy Dallas-area mall after a 33-year-old gunman opened fire, wounding at least seven others before he was fatally shot by police.

The previous weekend in Oklahoma, a convicted sex offender shot and killed his wife, her three children, and two of their friends before he killed himself, according to police.

 Just two days prior to that, a man shot and killed five neighbors, including a 9-year-old boy, after the family asked him to stop firing rounds in the air as a baby tried to sleep. The suspected shooter was arrested after a manhunt that lasted several days.

There have been more than 200 mass shootings in the US so far this year, according to the Gun Violence Archive, which defines a mass shooting as an incident in which four or more people are injured or killed, not including the shooter.

The threat of gun violence in conjunction with the perceived lack of security within the US is increasingly seen as a safety concern by both American citizens and would-be tourists.
