The cartel is also linked to other crimes including money laundering.
The group- which also included 13 Mexicans- was looking to import methamphetamines and ecstasy into Spain, via the ports in Barcelona and Tarragona.
On Tuesday, the brothers flew to Madrid via Budapest on a regular flight.
Operation Balkans continues to investigate the Sinaloa Cartel and its highly sophisticated operations in Spain.

Their mother of Hungarian descent enrolled them at a well-known and prestigious school in Budapest that was attended by diplomats and wealthy businessmen.
Their father, who ran drug trafficking from a Tarragona house, led them to a life of luxury and exclusivity while they hopped between Mexico City, Barcelona, and Budapest.
They did not hide the wealth of their brothers through their social media posts.
Both featured high-end Lexus vehicles, designer clothes and cigars, as well as five-star hotels. They also made references to cryptocurrency accounts that allegedly had transactions worth millions of dollars.
They were active participants in the distribution network of methamphetamine, and many tasks had been delegated to these two men by the Policia Nacional.
Cellular members received drug shipments from Mexico impregnated with different materials, which they then processed in secret laboratories in Catalunya, before distributing them around the world including to Australia.
