WARSAW (Reuters) - Polish officials have seized two tonnes of cocaine from Colombia worth around 2 billion zlotys ($510 million), Prime Minister Mateusz Morawiecki said on Thursday.

“This was the biggest amount of drugs seized in the last 30 years,” Morawiecki told a news conference, adding that the security forces have detained several suspects, including four Colombians, two Poles and one Iranian.
