A woman has been taken to hospital with serious injuries after being held hostage at her home in Kent, witnesses have said.
"Officers, along with a trained police negotiator, attended and attempted to engage with a man inside the address," a spokesperson for the force said.
"Officers remain at the scene and enquiries are ongoing to determine the circumstances surrounding the incident."
One woman, who wished to remain anonymous, described the scene as "chilling".
"I was in the house and my husband and two girls were out - they couldn't get back home," she said.
"I went out and was told 'get back - you must stay indoors'. I went to the garden where I could see more."
About an hour after police entered the property, she said she heard gunshots before a person was carried out on a stretcher.
