Mexico announces record drug seizure one week after Trump threatens tariffs

Soldiers and marines discover drugs in Sinaloa, while separately authorities arrest more than 5,200 migrants

Mexican security forces have impounded more than a ton of fentanyl pills in what officials have called the biggest seizure of the synthetic opioid in the country's history.

Soldiers and marines found the fentanyl at two properties in the northern state of Sinaloa, late on Tuesday - exactly a week after Donald Trump threatened to impose 25% tariffs on products from Canada and Mexico unless the two neighbouring countries cracked down on the flow of immigrants and drugs across their borders with the US.
