The Harford County Sheriff’s Office tweeted that there was a shooting Thursday morning in the city of Perryman that involves “multiple victims.”

The sheriff’s office warned that the situation is still fluid and ask people to avoid the area.

Several people were shot on Thursday in Perryman, Maryland, and residents were asked to avoid the area, according to US authorities.

“The situation is still fluid,” the Harford County Sheriff’s Office wrote on Twitter, adding that officers responded to the incident shortly after 9 a.m. EDT (1300 GMT).

Agents from the Baltimore office of the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) were also headed to the scene, the agency said.

Perryman is 34 miles (55 km) northeast of Baltimore. The area of the reported shooting includes a church and a business district, and is near the Aberdeen Proving Ground, a US Army facility.

The shooting occurred a day after a man entered a Pennsylvania court building and shot and wounded four people, including a police officer, before he was killed by police, according to Pennsylvania State Police.

The United States loses around 33,000 people to gun violence every year. Additionally, more than 100,000 people are shot each year in the country at a total cost of $45 billion, according to a study published in the journal Health Affairs.

Amnesty International said in a scathing report last week that the gun violence situation in the United States has grown into a full blown "human rights crisis" amid inaction from the US government.

The report said “all aspects of American life have been compromised in some way by the unfettered access to guns, with no attempts at meaningful national regulation.”

“The US government is prioritizing gun ownership over basic human rights. While many solutions have been offered, there has been a stunning lack of political will to save lives,” said Margaret Huang, executive director of Amnesty International USA.

"Our government has allowed gun violence to become a human rights crisis," she said.

The issue of gun violence has become all the more polarizing under President Donald Trump, a Republican whose presidential campaign was funded partially by the National Rifle Association (NRA).

Trump has been reluctant to address the growing issue in his speeches and following several high-profile mass shootings in the country.
