YEREVAN, MAY 25, ARMENPRESS. The brother of Salman Abedi, the suspect accused of carrying out a bombing in Manchester, England, that killed 22 people, allegedly said he knew his brother was going to carry out an attack, but did not know where or when, according to a spokesman for Libya's counterterror forces, ABC reported.

Abedi, 22, the suspected suicide bomber, died at the scene of Monday night's attack at an Ariana Grande concert.

The UK has declared a 'critical' level of terror threat.

The highest threat level, which is decided by the Joint Terrorism Analysis Centre - a group of experts from the police, government departments and agencies - has only been reached twice before.

22 people died when a suicide bomber detonated and IED in Manchester Arena, England, during a concert of US pop star Ariana Grande. More than 50 people have been injured.

Salman Abedi, the 22-year-old British man believed to have killed 22 people in a suicide-bomb attack in Manchester Arena, had ties to al Qaeda and had received terrorist training abroad, a U.S. intelligence official told NBC News on Tuesday as the United Kingdom raised its terrorist threat level to the highest category.
