(CNN) -- A standoff between an armed man allegedly barricaded in a New Jersey home with children stretched into a third day Sunday as negotiators tried to coax him to surrender.
The gunman was holding three children hostage in Trenton in a standoff that started Friday, authorities said.
Days later, Trenton police said they were still talking with the gunman.
Officials are working to have a peaceful ending, Trenton police Lt. Stephen Varn said.
While the situation inside the home was unclear, no officers have been injured, he said.
"We have state police on the scene, a SWAT team and a hostage negotiator present," Trenton police Lt. Mark Kieffer said Saturday. "We evacuated the surrounding blocks."
The ordeal began Friday afternoon, police said, but it was unclear how it started or how old the children are, or their relationship to the man.
No hostages have been released, authorities said.
