UK eases terror threat level
British Prime Minister Theresa May says the country's threat level from terrorism had been reduced from its top level of "critical," which indicates an attack is imminent.
May says it now stands at "severe," meaning an attack is highly likely.
The level was raised to critical after Monday's bomb attack in Manchester, which killed 22 people.
May says major progress has been made in the investigation but that people should remain vigilant.
