'We must act,' Biden says, after yet another mass shooting

Indianapolis: Multiple people shot at FedEx site, gunman dead

Indianapolis mass shooting: 'Emotions are very high' after shooting at FedEx facility

News of another US mass shooting has prompted US Vice President Kamala Harris to call for an end to American gun violence.

The former employee who shot and killed eight people at a FedEx facility in Indianapolis was interviewed by FBI agents a year ago, after his mother called police to say that her son might commit "suicide by cop", the bureau said Friday. Another two people were treated and released at the scene.

Police first responded to reports of a shooting at the FedEx facility around 11pm on Thursday, in the shadow of Indianapolis International Airport, in the southwest of the city.

Hole began firing randomly at people in the parking lot of the FedEx facility late Thursday, killing four, before entering the building, fatally shooting four more people and then turning the gun on himself, McCartt said.

She added that President Joe Biden will deliver remarks about the shooting later on Friday.

Another FedEx employee, Levi Miller, told NBC's "Today Show" he ducked out of sight when he saw a hooded figure holding what appeared to be an AR-style semiautomatic rifle who shouted and opened fire outside the facility.

"She got shot on her left arm", said Parminder Singh. Other injured people took themselves to hospitals in the area, she added.

Authorities searched multiple locations and seized evidence in their effort to learn more about the shooter and a possible motive. According to those reports, federal and local authorities learned of his history from one of his family members prior to the attack.

A FedEx employee said he was working inside the building Thursday night when he heard several gunshots in rapid succession.

"When you see notifications on your phone, but you're not getting a text back from your kid and you're not getting information and you still don't know where they are ... what are you supposed to do?" said Mindy Carson, holding back tears in the early hours of Friday.

She said that several of her family members work at the particular facility and are traumatised.

Indianapolis - the capital of the Midwestern state of IN - alone has seen two mass shootings this year.

Varun Nikore, executive director of the AAPI Victory Alliance, a national advocacy group for Asian Americans and Pacific Islanders, said in a statement that the shootings marked "yet another senseless massacre that has become a daily occurrence in this country".

The Indianapolis carnage follows a spate of mass shootings across the U.S. in recent weeks, including at an office building in southern California, a grocery store in Boulder, Colorado and at several spas in Atlanta, Georgia where eight people, including six women of Asian descent, were killed.

That was followed by the killing of ten people including a police officer by a Syrian immigrant in Boulder, Colorado State.

In a tweet, Jaishankar wrote, "Deeply shocked by the shooting incident at FedEx facility in Indianapolis". Justice must be served and we will not stop fighting until every single gutless person, politician, and lobbying group is held responsible for continuing to allow these tragedies to happen.
