Twenty-four New Yorkers were hit by gunfire, one fatally, over 24 hours of  violence this weekend, prompting Mayor  Bloomberg to call the bloody stretch “unconscionable” and demand action from  Washington.

The  eruption of shootings from 6 a.m. Saturday to 6 a.m. Sunday left the mayor livid  and the parents of three wounded children distraught and angry.

Police  said the two dozen victims were shot in 14 separate incidents in Brooklyn,  Queens and the Bronx.  As of last night, no arrests had been made in any of the  shootings.

“These people come with guns and shoot at anyone. They don’t  care if there are children around,” said Charles  Walters, 53, whose 11-year-old son, Shaquan, was the youngest of eight  people wounded early yesterday at a backyard party in the Bronx by a lone  gunman.

Shaquan was shot in the right leg and was recovering yesterday at  Jacobi  Medical Center. A 14-year-old girl was shot in the back and a 13-year-old  girl was wounded in the left thigh in the 3:39 a.m. barrage.

Five young  men – ages 17, 18, 19, 21 and 24 – were also wounded in the shooting on E. 221st  St. in Williamsbridge and taken to local hospitals, cops said. They were expected to  survive.

As police hunted for the suspect, who they identified as  17-year-old Oneil  Dasilva of Mount  Vernon, Bloomberg went ballistic yesterday, demanding stiffer federal gun  laws.

The mayor said 24 people shot in 24 hours in the city “is just  unconscionable.”

“We cannot tolerate it,” Bloomberg said while speaking  at the Christian  Cultural Center in Brooklyn. “There are just too many guns on the streets  and we have to do something about it.”

New  York has the toughest gun laws in the country, but Bloomberg said the city  alone cannot stop the onslaught of shootings. “We need the federal government to  step up,” he said.

Bloomberg is a co-chair of Mayors  Against Illegal Guns and has lobbied Washington repeatedly to beef up gun  laws.

The mayor called on all federal politicians, regardless of party,  to get on the same page .

“Both ends of Pennsylvania Ave., both sides of  the aisle,” he said. “We cannot continue to have these guns in the hands of kids  who don’t understand the value of life.”

Overall, gun violence in the  city is down 5.9% from last year. As of Aug. 28, 1,123 people had been shot in  New York this year, according to the NYPD.

In  the 24 hours of bloodshed, only one victim was fatally shot, a 30-year-old man  found just after 2 a.m. yesterday with bullet wounds in the head and back in a  home on E. 93rd St. in Flatbush.

The  cycle of gun violence began about 6 a.m. Saturday when a 35-year-old woman was  shot and wounded at Saratoga Ave. and Newport St. in Brooklyn.

During  one 18-minute stretch between 2:12 a.m. and 2:30 a.m. yesterday, five men were  shot in three separate incidents, including three wounded at a house on Beach  Channel Drive in Rockaway  Park, Queens.

Many are comparing this incident to a new movie called “The Purge” all emergency services becomes suspended and violence becomes legal for certain amount of hours.
