YUMA, Ariz. (AP) - Suspected smugglers tried to use ramps to drive an SUV over a 14-foot-tall fence along the U.S.-Mexico border, but they had to abandon the effort when the Jeep got stuck on top of the barrier.

U.S. Border Patrol spokesman Spencer Tippets says patrolling agents spotted the Jeep Cherokee perched atop the fence early Tuesday. It was about five miles west of the Colorado River, which divides Arizona and California.

Two people on the Mexican side were trying to free the Jeep when the agents approached. They ran further into Mexico.

The Jeep was empty, but agents say it was probably filled with contraband like marijuana before it got stuck.

The smugglers had built ramps that looked like long ladders to drive up and over the fence, but the SUV became high-centered at the top.
