A teenage girl has pleaded guilty to two terror offences including possessing "recipes for explosives" and a bomb-making guide.

The 16-year-old, from Manchester, admitted the charges at the city's Magistrates' Court.

She was arrested in April following an investigation by the North West Counter Terrorism Unit.

The inquiry also led to the arrest of a boy, 14, who admitted involvement in a plot to attack police in Australia.

The court heard that phone data retrieved by police showed the pair exchanged more than 2,000 WhatsApp messages a day before being arrested.

No evidence was found that the girl was aware or played any part in the Anzac Day plot or any plan to harm others or incite terrorism in the UK or elsewhere, the court was told.

The girl, who cannot be named, admitted two counts of possessing a document containing information of a kind likely to be of use to a person preparing or committing an act of terrorism.

She used her school's IT system to search for information on Jihadi John, the so-called Islamic State (IS) group and images of Michael Adebolajo, who killed Fusilier Lee Rigby in Woolwich in 2013.

Analysis of her mobile phone found instructions for producing a timed circuit, a document about DIY bomb-making and the Anarchist Cookbook 2000.

The girl also had images of guns, knives and grenades.

Photos of a dead child and an execution were also recovered, the court heard.

The judge warned her that his sentencing options would include "immediate custody".

She was bailed until sentencing on 15 October.

Her bail conditions include ban on travel outside England and Wales, and on applying for travel documents.
