As many as eight people have been gunned down in separate drug-related shootouts in the Mexican city of Juarez as the country scrambles to snuff out drug trafficking. Five men were killed at a tire repair shop in Juarez on Sunday and three others were slain in a house on the outskirts of the border city in a separate incident. Meanwhile, the Mexican army found the bodies of five men in a graveyard south of Palomas, Chihuahua. The upsurge of drug-related violence comes despite efforts by Mexican President Felipe Calderon, who launched a war on drug cartels in the country in 2006. Drug-related violence has so far claimed some 31,000 lives in spite of Calderon's deployment of about 50,000 troops across the country.
