British police investigating the lethal concert bombing in Manchester have said that they have made two more arrests.
In the United Kingdom, eight people are now in custody after two more men were arrested overnight in Greater Manchester.
Meanwhile, Senior police chiefs in Britain reacted with anger Wednesday night after sensitive details of the Manchester Arena suicide bombing were leaked to media in the U.S.
After arresting a 23-year-old man on Tuesday, police said they had taken three more men into custody on Wednesday in south Manchester, the area where Abedi lived.
Various media outlets reported that police had found a kind of bomb-making workshop in Abedi's home and he had apparently stockpiled enough chemicals to make additional bombs.
"Due to the tragic events in Manchester the Dangerous Woman tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost".
In her first substantive comments since Monday's attack claimed by the Islamic State (IS) group, Grande hailed the compassionate spirit of her fans and vowed not to give in to divisions.
Manchester terrorist Salman Abedi called his mother before the attack and asked her to "forgive me", Libyan anti-terror police have said.
Monday's attack, which killed 22, was the deadliest in Britain since 2005 when four Islamist suicide bombers attacked London's transport system, killing 52 people. "We aren't the ones who blow up ourselves among innocents".
"I have been thinking of my fans, and of you all, nonstop over the past week", she told fans. His father, Ramadan, told the Associated Press that Abedi was getting ready to go to Saudi Arabia, and then planned to come back to Libya. "He saw the explosives America drops on children in Syria, and he wanted revenge", Jomana Abedi told the Wall Street Journal.
German authorities are now trying to determine whether Abedi had contact with Islamic extremists in Germany before flying to Manchester last week, the magazine said.
British officials are particularly angry that photos detailing evidence about the bomb used in the Manchester attack were published in the New York Times, although it's not clear that the paper obtained the photos from USA officials.
"The British police have been very clear they want to control the flow of information in order to protect operational integrity - the element of surprise - so it is irritating if it gets released from other sources, and I've been very clear with our friends that that should not happen again".
