The condition of a Virginia teacher left seriously injured when she was shot by a six-year-old pupil has shown signs of improvement, authorities say.

Abby Zwerner suffered life-threatening injuries after she was shot with a handgun at Richneck Elementary School in the city of Newport News on Friday.

Mayor Phillip Jones told the BBC that Ms Zwerner's recovery was "trending in a positive direction".

But he added that she remained in a critical condition after the incident.

Online, social media users wished Ms Zwerner - who is believed to be in her 30s - a speedy recovery.

Her alma mater, James Madison University in Virginia, offered "prayers and best wishes for Abby's health and recovery".

It is unclear how the child - who remains in police custody - obtained the gun. Officials said that while the school - which has around 550 students - had metal detection facilities, students were checked at random and not every child was inspected.

Police have declined to say what might have motivated the incident, but Chief Steve Drew told reporters the shooting had come after an "altercation" in a first grade (ages six to seven) classroom and did not appear to be "accidental".
