Roundup: Teen party shooting in Florida contributes to high profile shooting incidents in U.S.

At least two people were killed and 19 others injured in a shooting incident at a nightclub hosting a teen party Monday in Fort Myers, Florida.

The shooting took place at a parking lot of Club Blu just after 00:30 a.m. local time (0430 GMT) on Monday morning.

Police have detained three people after the attack, but it is still unclear who is responsible for the incident.

It has been the second mass shooting incident in Florida this year. The first one took place last month, in which an Afghan-American man named Omar Mateen of Port St. Lucie attacked a gay club in Orlando on June 12, claiming 50 lives and causing 53 injuries.

The shooting began at around 2:00 a.m. local time (0600 GMT) on June 12. Mateen was found dead in the nightclub after a shootout with the police.

The terrorist group the Islamic State has claimed responsibility for the Orlando nightclub massacre, and the FBI was "highly confident" that Mateen had been radicalized online.

On July 7, a sniper named Micah Johnson, upset over the police shooting incidents in Louisiana and Minnesota on July 5-6 which caused the deaths of two black men, ambushed and killed five police officers and wounded seven others and two civilians in Dallas, Texas.

According to the group Mass Shooting Tracker, there have been as many as 207 mass shooting incidents in the United States so far this year, while the Orlando attack has been the deadliest in the U.S. history.

In the past five years, an average of about 33,000 people were killed by guns each year in the United States, according to the data released by the U.S. Center of Disease Control.

Due to an increasing number of shooting accidents, satisfaction with the country remains low, as only twenty-one percent of U.S. voters think the country is headed in the right direction, the lowest level of confidence in nearly three years of surveying, according to a new Rasmussen Reports survey released last Saturday.

Following the successive mass shootings, a debate over gun control has been aroused nationwide. According to the Rasmussen Reports survey, fifty-six percent of voters said the country needs stricter gun control, reaching the highest level of support ever. Still, voters were evenly divided over whether more gun purchase restrictions will help prevent future shooting incidents.

The gun legislation failed again as four gun-control measures were blocked by the U.S. Senate on July 20. The measures include whether to expand background check and to block the selling of firearms to anyone on federal government's terrorism watch list. Endi
