Three major U.S. cities struggling to curb a surge in gun violence collectively had at least 70 people shot, 16 dead, including a 7-year-old girl, in multiple shootings this weekend, according to police.
The shootings in New York, Philadelphia and Chicago came as all three cities have seen sharp increases in the numbers of shootings in 2021.
In Chicago, at least 52 people were shot between 6 p.m. on Friday and 11:59 p.m. Sunday, nine of them fatally, according to the Chicago Police Department. Twenty-three of the shootings occurred over just a 4-hour period between 12:26 a.m. and 4:30 a.m. on Sunday, according to incident reports reviewed by ABC News.
Just before 3 p.m. on Sunday, a 7-year-old girl was killed and her 6-year-old sister was seriously wounded when someone opened fire on a parked vehicle they were sitting in the Belmont Central neighborhood on the city's Northwest Side, police said. The 7-year-old was shot in the chest and later died at a hospital.
One resident who lives near the shooting scene said the barrage of gunfire sounded "like a machine gun going off."
Regina Broughton told ABC station WLS in Chicago that her granddaughter, Serenity Broughton, was the child who was killed and Serenity's little sister, Aubrey, is fighting for her life at Loyola University Medical Center in Chicago.
"I'm lost, I'm lost... I mean they were my life, my everything," Broughton told WLS. "How do you prepare yourself for something like this? She was a beautiful child. Her spirit was beautiful, innocent, everything about her was innocent."
Chicago police Chief of Patrol Brian McDermott pleaded for the public to help the police solve the shooting.
"To say that I am saddened and outraged would be an understatement," McDermott said at a news conference Sunday night. "I can only hope that every resident of this city is angry, saddened and outraged as I am at this time."
Police did not comment on a possible motive.
More than 250 children have been shot and 32 killed in Chicago this year, according to police data obtained by ABC station WLS.
Prior to this weekend, more than 2,123 people had been shot in Chicago this year, which is a 12% increase from the same time period in 2020, according to police department crime statistics. Before this weekend, Chicago has recorded 478 homicides, a 2% increase over last year at this time.
The shootings this weekend in Chicago followed last weekend's violence, which saw 73 people shot in the city, 11 fatally.
Chicago police Officer Ella French was among those gunned down last weekend when she and her two partners pulled over a car for having expired tags. One of French's partners, a 39-year-old officer, was shot in the eye and remains in a hospital in critical condition with a bullet lodged in his brain, police said. Two brothers were arrested and charged in French's slaying.

Last month, Police Superintendent David Brown assembled a team of 50 officers to target gun traffickers, straw buyers, unscrupulous licensed firearms dealers and anyone who facilitates the flow of illegal guns into the city of Chicago.
Entering the weekend, 1,333 people had been shot in Philadelphia this year, a 19% increase from the same period a year ago, according to police department crime statistics. By the end of Friday, the city had recorded 329 homicides, a 26% increase from the same time period in 2020, the data shows.
Eleven more people were shot in Philadelphia over the weekend, five fatally, according to police.
"We need to stop this," Philadelphia resident and retired Marine Jamal Johnson told ABC station WPVI in Philadelphia.
The weekend gun violence came as Johnson and a group of supporters are marching to Washington, D.C., to draw attention to the escalating number of shootings and killings in their city. Johnson calls his action the "Stop Killing us March" and hopes to meet with members of the Congressional Black Caucus when he reaches the U.S. Capitol later this month.
"I would personally like them to encourage (Philadelphia) Mayor (Jim) Kenney to declare a state of emergency in Philadelphia due to gun violence," Johnson said. "Most of all to save the lives of our children."
Kenney said during a news conference last month that the city allocated over $150 million in its fiscal year 2022 budget to address gun violence. He said he has spoken to President Joe Biden "on the urgent need for new and enhanced approaches" to combat the problem.

In New York City, where more than 1,100 people have been shot this year, an 11% increase from a year ago, police said 15 more people were shot, three fatally, in 11 separate incidents on Friday night alone. The three homicides occurred in just 4 1/2 hours.

The victim, whose name was not immediately released, was pronounced dead at the scene, police said.
