LONDON - The latest on the suicide bombing at a concert in Manchester, England (all times local):

11:55 p.m.

A U.S. congressman says the bomb used in the deadly Manchester Arena attack in England suggests a "level of sophistication" that might indicate its maker had foreign training.

Texas Republican Mike McCaul, chairman of the House Homeland Security Committee, told The Associated Press on Wednesday that the bomb that killed 22 people and the alleged attacker was "a classic explosive device used by terrorists."

McCaul said the device used the explosive TATP, the same one used in the deadly November 2015 attacks in Paris and the March 2016 attack in Brussels carried out by Islamic State extremists.

McCaul was due to get an intelligence briefing on the Manchester attack later Wednesday.

He says the evidence so far suggests "we're not dealing with a lone wolf situation."

Echoing the comments of British officials, he said: "There's a network -- a cell of ISIS-inspired terrorists."

11:15 p.m.

British police have arrested a seventh person in connection with the Manchester Arena bombing.

The man was held Wednesday after police carried out searches in the English town of Nuneaton, which is about 161 kilometres (100 miles) south of Manchester.

His arrest was the first in England to take place outside of Manchester since the bombing.

Greater Manchester Police says six men and one woman remain in custody as the department investigates the Monday night bombing that killed 22 people.

The attack took place at the end of a concert by American singer Ariana Grande.

10:50 p.m.

A British broadcaster has obtained security camera footage that it says police believe shows the suspect in the Manchester Arena bombing wearing a backpack that was used in the attack.

Sky News on Wednesday aired two screengrabs of a man walking in Manchester's Arndale shopping centre on Friday night carrying a blue backpack with a sales tag still hanging off of it.

Sky did not say how in its report how it obtained the footage.

But the broadcaster reported that police think the man is alleged bomber Salman Albedi and the backpack played a role in Monday's attack after an Ariana Grande concert.

Twenty-two people were killed in the attack. Police say Albedi also died.

9:45 p.m.

Police in Manchester say a woman has been arrested in connection with the arena bombing that killed 22 people.

The 23-year-old pop star is on a European leg of her "Dangerous Woman Tour" and cancelled shows scheduled for Thursday and Friday at the 02 Arena in London.

The suspended tour means she also will miss a May 28 stop in Antwerp, Belgium, two concerts in Lodz, Poland, and shows in Frankfurt, Germany, and Zurich, Switzerland.

Grande has kept a low profile since Monday's Manchester Arena blast, which killed 22 people.

She took to Twitter afterward to say she was "broken" and "i don't have words."

A Libyan anti-terror force that arrested the brother of the alleged Manchester bomber says he had links to the Islamic State extremist group and was aware of his brother's plans.

British authorities have identified 22-year-old Salman Abedi as the suspected bomber in the attack at Manchester arena on Monday night.

The force's statement says: "The brother was aware of all the details of the terrorist attack."

Before his arrest, the father told the AP that his son was innocent and had been planning a trip to Saudi Arabia for a pilgrimage.

Ramadan Abedi also had said he worked as the administrative manager of the Central Security force in Tripoli.

He said he fled Tripoli in 1993 after Moammar Gadhafi's security authorities issued an arrest warrant and eventually sought political asylum in Britain.

Salman Abedi was born in Britain in died in Monday's attack at Manchester Arena.

Two of his brothers have been arrested along with their father.

A former Libyan security official says the father of the alleged Manchester arena bomber was allegedly a member of a former al Qaeda-backed group in Libya.

Former Libyan security official Abdel-Basit Haroun said Wednesday he personally knew Ramadan Abedi, the father of Salman Abedi, and that the elder Abedi was a member of the Libyan Islamic Fighting group in the 1990s. The group had links to al Qaeda.

Although the LIFG disbanded, Haroun says the father belongs to the Salafi Jihadi movement, the most extreme sect of Salafism and from which al Qaeda and the Islamic State group hail.

He said that his son visited Libya a month-and-a -half ago.

The elder Abedi told The Associated Press by telephone from Tripoli: "We don't believe in killing innocents. This is not us."

He said his other son, Ismail, was arrested in England on Tuesday morning.

He said Salman was planning to head from Saudi Arabia to Libya to spend the holy month of Ramadan with family.

Abedi fled Tripoli in 1993 after Moammar Gadhafi's security authorities issued an arrest warrant and eventually sought political asylum in Britain.

Now, he is the administrative manager of the Central Security force in Tripoli.

Israel's defence minister says he doubts the devastating bombing in Manchester will have any impact on European counterterrorism tactics because of the continent's "politically correct" character.

He said nothing will change until these residents are ready to adopt "universal, European values."
