Drug traffickers are going medieval in their attempts to smuggle marijuana into the U.S.

Last week, U.S. Border Patrol agents caught a group catapulting bags of weed over the border fence from Mexico, near the Douglas Port of Entry in Arizona.

According to a press release, American agents were patrolling the U.S. side of the wall on February 10 when they saw a group scatter on the Mexican side.

When they got to the point in the fence where the group had been, they found that a catapult had been rigged to the fence on the Mexican side.

Not far away, they seized two bundles of marijuana - weighing a combined 47 pounds.

U.S. Border Patrol agents dismantled the catapult, but then let it fall on the Mexico side for police there to seize, since it was on their side of the fence.

Federal authorities say smugglers have gone to great measures to sneak drugs in to the country in recent years, employing catapults like the one found last week, as well as air-powered cannons, ramps and ultralight aircraft.

The use of such measures throws a wrench in President Trump's plan to stop illegal immigrants and drug smugglers from getting into the country by building a bigger wall along the border.
