WASHINGTON (CNN)  -- U.S. authorities have ratcheted up pressure on one of Mexico's most notorious drug cartels, releasing new details about the so-called Gulf Cartel's operations and offering up to a $50 million reward for the arrest of its leaders. These are weapons that the Mexican army said it seized from the ruthless Gulf Cartel in 2008. A federal indictment unsealed Monday charged Miguel Trevino Morales, a leader of the northern Mexico-based Gulf Cartel, of operating a criminal enterprise, cocaine distribution and firearms violations. Concurrently, prosecutors updated a separate indictment against three other top leaders of the Gulf Cartel: Antonio Cardenas Guillen, Jorge Eduardo Costilla and Heriberto Lazcano, for drug trafficking related crimes, all believed to be at large in Mexico. Fifteen other suspected cartel members are also named in that indictment. "We have learned that the most effective way to disrupt and dismantle criminal organizations is to prosecute their leaders and seize their funding," Assistant Attorney General Lanny Breuer said in a statement. To that end, the departments of justice, state and treasury are working together to place pressure on the Gulf Cartel and what authorities describe as its ruthless enforcement arm, known as Los Zetas. The Department of the Treasury designated the four top bosses named in the indictments as Specially Designated Narcotics Traffickers, which authorizes the freezing of any assets they hold in the United States and other sanctions. The Gulf Cartel and Zetas, nicknamed collectively as "The Company," are among the major drug cartels that are behind the drug-related violence that has swept Mexico in recent years, according to authorities. Since taking office in 2006, Mexican President Felipe Calderon has made fighting the cartels a major priority. The group also operates in cities across the United States, authorities said. The court documents detail telephone conversations between the four leaders and more than a dozen other cartel members allegedly discussing the transportation and smuggling of cocaine and marijuana into the United States. "These indictments allege a stunning and sophisticated operation by 'The Company' to move illegal drugs into our communities and cash back to Mexico," Breuer said. The State Department is offering a rewards totaling up to $50 million for information leading to the capture of four top leaders and six other cartel lieutenants.

Ladies and gentlemen, the Rolling Stones are back on tour. The "world's greatest rock 'n' roll band" resumed its #StonesOnFire trek, part of its 50th-anniversary travels around the globe, with a show Monday night in Oslo, Norway. The group's tour had been put on hold since the March 17 death of Mick Jagger's girlfriend, fashion designer L'Wren Scott. Scott's death, which was ruled a suicide, stunned Jagger, who had been with the designer and former model since 2003. "I am still struggling to understand how my lover and best friend could end her life in this tragic way. We spent many wonderful years together and had made a great life for ourselves. She had great presence and her talent was much admired, not least by me," he said in a statement two months ago. Scott left her $9 million estate to Jagger, according to the late fashion designer's will. Though she had reportedly been having financial difficulties, a representative for Scott said, "The figures quoted in the media regarding the financial status of LS Fashion Limited are not only highly misleading and inaccurate but also extremely hurtful and disrespectful to the memory of L'Wren Scott." The Stones were in Australia at the time of her death, and the band canceled seven shows there and in New Zealand. The shows have been rescheduled for October and November, according to the Stones' official site. The Stones' Oslo set list included "Jumpin' Jack Flash," "All Down the Line," "Let's Spend the Night Together," "Emotional Rescue" and a version of "You Can't Always Get What You Want" accompanied by the Edvard Grieg Youth Choir.
