The UK is planning to conduct military exercises that will include, among other things, launches of Rapier Anti-Air missiles, between October 19 and October 28. According to Argentinian position, the planned exercises are viewed as UK military operation on Argentinian territory illegally occupied by the United Kingdom.
The UK, however, claims the exercises are a "routine operation" that takes place twice a year and that Argentinian government has been properly notified of the upcoming military activity.
Argentina has claimed sovereignty over Falklands, located some 435 miles from country's mainland, for decades, which has even led to a short, but terrible war in 1982. However, the majority of the islands' population wants them to remain under control of the United Kingdom.
Previous president of Argentina, Cristina Fernandez de Kirchner, fueled tensions over the islands over the term of her presidency. The new president, Mauricio Macri, however, displayed a more business-like approach, seeking to open new channels of communication between Argentina and the UK.
However, last month Macri claimed that he and British Prime Minister Theresa May agreed to discuss the Falklands sovereignty issue, but this claim has been later disavowed by Argentinian Foreign Ministry.
