United Kingdom security agency investigates failures to stop bomber

After raiding various addresses in the northwestern English city, police arrested two men aged 25 and 19, bringing the number now detained on United Kingdom soil to 13.

Authorities detained a 23-year-old in the southern coastal town of Shoreham-by-Sea, more than 400 kilometers (250 miles) from Manchester.

The Monday arrest has brought the total number of people arrested in connection with the Manchester bombing to 16.

This is a handout photo taken from CCTV and issued on Saturday, May 27, 2017 by Greater Manchester Police who have altered the surrounding area of Salman Abedi, in an unknown location on the night of the attack on Manchester Arena. The bombing killed 22 people, including children.

In a statement, police said: "The investigation is making good progress and we know one of the last places Abedi went was a city center flat and from there he left to make his way to the Manchester Arena".

Interior Minister Amber Rudd said MI5 was right to review the way it had dealt with Abedi in the past despite it being unusual for authorities to announce an internal security service investigation.

Last week, the Royal Air Force scrawled the message "love from Manchester" on a Paveway IV bomb meant for airstrikes against the Islamic State in Cyprus, Italy.

On Sunday, police released photographs from security cameras showing Abedi on the night of the massacre, wearing jeans and trainers, a black body warmer and a baseball cap, with the straps of his backpack visible on his shoulders.

Abedi, a 22-year-old Briton of Libyan descent, killed 22 people and himself on May 22 at an Ariana Grande concert.

"The intelligence services are still collecting information about him but I wouldn't rush to conclusions, as you seem to be, that they have somehow missed something", Rudd said.

The bombing was the latest in a series of IS-claimed attacks in Europe that have coincided with a US-led offensive against the jihadist group in Syria and Iraq.

Abedi spent time in Libya before the attack and traveled through Istanbul and Dusseldorf airports on his way back to Britain. But it still remains at "severe", meaning an attack is highly likely.

Britain has downgraded its national security level from its highest level.

The government is facing criticism after acknowledging that Abedi was on security services' radar, but wasn't a major focus of investigation.
