A couple from Poland named as victims in the Manchester attack were killed as they waited to collect their daughters from the concert, the country’s foreign minister has said.

Angelika and Marcin Klis died when a suicide bomber detonated a device as crowds were leaving an Ariana Grande gig.

Details of their deaths emerged as the names of several other victims of Monday’s attack were confirmed by police and grieving family members.

Polish Foreign Minister Witold Waszczykowski said the couple’s two girls were safe after the explosion that left 22 dead and 64 injured.

He told a Polish radio station: “The parents came after the concert to collect their daughters and unfortunately we have information that they are dead.

“The children are safe.”

Another Polish citizen was wounded in the attack and has undergone surgery in a hospital. He is a father but no further details about his identity have been released.

A spokesman for the country's foreign ministry said: “at least two people have died and one person has been injured" but did not confirm any further details.

On Tuesday, York College student Alex Klis said she was looking for her parents Angelika and Marcin, who had been missing since the attack.

“Anyone who is in any safe place or hospital in Manchester, if anyone comes across my parents please please let me know as they've been missing ever since the attack,” the 20-year-old wrote on Facebook.
