Supporters of leftist Mexican presidential candidate Andres Manuel Lopez Obrador have taken over toll booths in Mexico City.

Activists opened toll barriers across three highways going in and out of the capital Tuesday, letting drivers go through without paying.

Lopez Obrador's supporters have protested for a recount since the July second presidential election, which they allege was fraudulent. A spokesman for his Democratic Revolutionary Party said today's action was part of those protests. It was the first time the protesters have disrupted federal facilities.

Lopez Obrador lost the election by about a half-percentage point to conservative Felipe Calderon. He has demanded a recount of all 41 million ballots cast, but Mexico's electoral commission ruled last week that a recount will only take place in about nine percent of the country's 130,000 voting stations.
