The young man who killed 27 people in a massacre in Newtown, Connecticut, last December, owned an arsenal of weapons and ammunition, court papers have shown.

President Barack Obama called the day of the shootings the worst of his presidency and launched a campaign to tighten gun laws in the wake of the attack.

Mr Obama said he had not forgotten the children who had died during the mass shooting.
