The UK government is warning the US against leaking further details from the investigation into the Manchester bombing.

British police say the leaks are undermining their inquiry into a network linked to the alleged suicide bomber - Salman Abedi.

The New York Times has published photographs said to show fragments of what has been described as a sophisticated device used in the attack.

Seven people have now been arrested in the UK in connection with the bombing, which killed 22 people and injured 64 others on Monday.
