British Prime Minister Theresa May said that progress has been made since Monday's suicide bombing after an Ariana Grande concert.
"A significant amount of police activity has taken place over the last 24 hours and there are now 11 suspects in custody. In the light of these developments, JTAC, the independent joint terrorism analysis center, has this morning taken the decision to reduce the threat level from critical to severe."
Soldiers who have been helping police will be withdrawn from Britain's streets in the next few days.
A militia in Libya has detained bomber Salman Abedi's father and brother. But details on how they may be tied to the bombing have not been released.
Grande says she will return to Manchester to do a benefit show to raise money for the victims and their families. But the date has not been set.

U.S. National Security Advisor H.R. McMaster said Saturday he was not concerned about a The Washington Post report that President Donald Trump's son-in-law and senior adviser, Jared Kushner, discussed with Russia's ambassador to Washington the possibility of setting up a secret communications channel between the Trump transition team and the Kremlin.
"We have back-channel communications with any number of countries. So generally speaking, about back-channel communications, what that allows you to do is communicate in a discreet manner. So it doesn't pre-expose you to any sort of content or any kind of conversation or anything. So we're not concerned about it."
McMaster said he would not comment specifically on Kushner.
The Post quoted U.S. officials Friday as saying that the move was meant to shield pre-inauguration discussions from scrutiny.
