At least 30 people were injured, two fatally, when a mass shooting erupted early Sunday at a block party in Baltimore, according to police. An 18-year-old girl was found dead at the scene from a gunshot wound and a 20-year-old man was taken to a hospital, where he died, authorities said. The mass shooting unfolded around 12:30 a.m. in the Brooklyn Homes neighborhood in the southern district of the city.

A mass shooting at a Valero gas station in Oakland, California that left one dead and seven others injured happened while a music video was being filmed, reports say.

California has some of the most dangerous cities in the county and some of its safest, according to a new study. San Bernardino and Los Angeles were ranked among the most dangerous.

The shooting took place at 12:45pm yesterday at Rudsdale Newcomer High School in East Oakland. Three of the victims are aged 18, 19 and 58 years old. Police are seeking at least one suspect.
