Police in the U.S. state of Connecticut have been speaking about the ongoing investigation into the shooting of 20 young children and 6 adults at an elementary school in Newtown Connecticut on Friday. Those killed at the school have now been identified and their next of kin informed. This report from Jonny Dymond.

All night police worked at Sandy Hook Elementary School, gathering evidence and removing the bodies of the children and their teachers. All the families have now been told of their loss. The state police say they have what they call very good evidence from both the school and the alleged killer's home, where his mother's body was found. The gunman, they say, forced his way into the school yesterday by breaking a window. The town of Sandy Hook is quiet. Many shops are closed today. And many residents have appeared to be staying in their homes.

Several politicians have called for changes to America's gun laws to prevent shootings similar to Friday's. President Obama made an appeal for meaningful action to prevent more deaths, regardless of politics. From Washington, Paul Adams.

In his weekly address from the White House, President Obama repeated the language he used last night. Free from the constraints of re-election, it's possible he'll try to act more forcefully.But Support for stricter gun legislation has actually fallen, not risen, in recent years, along with the steady decline in overall levels of violent crime. The gun lobby has a powerful grip on Congress. And the last time the issue came before the Supreme Court, the justices ruled in favor of the individual's right to bear arms.
