The most common method of killing another person from 2010 through 2016 was by using a gun, says the US Centers for Disease Control and Prevention.

State laws that require gun purchasers to obtain a license contingent on passing a background check performed by state or local law enforcement are associated with a 14 percent reduction in firearm homicides in large, urban counties, says a new study from the Johns Hopkins Bloomberg School of Public Health.

Homicides across dozens of U.S. cities increased by nine percent over the first three months of 2016 compared to the same period last year.

A new report says that terrorism continues to rise, with over 32,000 people killed in terrorist attacks in 2014, the highest number recorded.

Homicide and assault rates have decreased significantly since 1980, but overall rates of violence remain high. 

The number of homicides decreased, while kidnappings increased, in Mexico in 2013.

Murders across the United States dropped by almost half between 1992 and 2011.

The report calls for more background checks and stronger controls over certain high-risk groups such as convicted criminals and younger age groups.

Chicago is calling in extra help after the city's homicide rate outpaces New York City, which has twice as many people as Chicago.

Police report 120 homicides in Chicago from January 1 to April 1, 2012, 60 percent higher than the same period in 2011.
