The band's Sport Colombia stadium show in Asuncion came to an abrupt end as fans rushed the stage, causing a reported stampede that left several people injured.

MEGADETH frontman Dave Mustaine took to Twitter to explain the group's decision to end the gig, writing: "After all three barricades broke and hundreds of fans crushed three security guards, almost killing one female fan, we regretfully had to cancel the show.

"Please understand that your safety is just as important as ours and after all the security went in the pit someone ran onto the stage, a bottle was thrown, and we'll let you know as soon as we can reschedule and come back."

Mustaine has pledged "use a different venue, security, and promoter" when the band returns to the city.
