Halifax Town Hall flags to fly at half mast today in honour of London terror attack victims

The council announced the decision that the flags will be lowered to half mast today.

Seven people have been arrested in raids in London, Birmingham and elsewhere linked to the Westminster terror attack, police have revealed.

Mark Rowley, the Met’s senior anti-terror officer, said six addresses were raided overnight.

He spoke as MPs were returning to Parliament in a show of defiance.

Mr Rowley revised the death toll down from five to four - the attacker, Pc Keith Palmer, who he stabbed, and a woman in her mid 40s and a man in his mid 50s, who were mown down as the terrorist sped across Westminster Bridge in his car.

He said 29 people had been treated in hospital with seven people in a critical condition.

Mr Rowley said it was still his belief the attacker worked alone and was inspired by “international terrorism”, adding that there was no specific information to suggest any further threat to the public.
