Toronto's crack-smoking mayor faced new embarrassment Thursday when video footage was published showing him in an agitated state, staggering and making foul-mouthed threats.

Rob Ford, who admitted earlier this week that he had smoked crack cocaine while on a drunken binge, said he had been "extremely, extremely inebriated" when the video was shot.

"It's extremely embarrassing and I don't know what to say," Ford told reporters outside his office, after seeing the one minute 17 second clip.

The video purchased and released by the daily Toronto Star shows Ford staggering around an unknown living room, ranting and making punching gestures.

"I'll rip his fucking throat out. I'll poke his eyes out... I'll make sure that motherfucker's dead," Ford says, in a tirade apparently secretly videotaped by someone in the room.

"I'm gonna kill that fucking guy. I'm telling you, it's first-degree murder," he says.

This video comes after Ford on Tuesday admitted that he once smoked crack "probably in one of my drunken stupors."

The admission by the 44-year-old came after repeated denials, and six months after another video surfaced that allegedly showed him consuming the illicit drug.

The first video is now in police possession as part of an investigation of Ford's longtime friend Alexander Lisi for extortion, related to Lisi's attempts to recover the video.
