Council leader Barrie Grunewald has offered his condolences to the people of Belgium after Tuesday’s terror attack.
Coun Grunewald was travelling into the city on Labour Party business as the terrorists struck at Zavantem Airport.
He and fellow St Helens councillor John Fulham - together with a group of 26 other Labour politicians - were on their way to meet with members of the EU Parliament.
They touched down at nearby Charleroi Airport.
“We learned of these terrible events just after we landed,” said Coun Grunewald.
“Our thoughts and prayers go out to the families and friends of those killed and injured in this atrocity.”
St Helens Council has been flying the flag at half-mast above the town hall as a mark of respect to victims of the attack.
