WESTMINSTER was in lockdown yesterday (Wednesday) after a policeman was stabbed to death and his apparent attacker shot by officers in a major security incident at the Houses of Parliament.

Four people are dead: the police officer, the attacker and two people who were mown down as the attacker drove a grey Hyundai i40 across Westminster Bridge before crashing it into railings.

Eyewitnesses said he was shot by police as he approached a second officer clutching his knife.

The attacker left a trail of destruction as paramedics tended to his victims on the bridge and at the gate.

ISIS has since claimed responsibility for the attack.

Fermanagh south Tyrone Ulster Unionist MP Tom Elliott spoke to The Impartial Reporter from inside Westminster, where “a massive security operation” had been “rolled out very quickly” and the atmosphere was “tense”.

It’s bedlam,” said Mr. Elliott as he was ushered out of his office by security officers and ordered to stand on a stairwell with hundreds of other MPs.

“These incidents are obviously very concerning indeed, coming as they do on the first anniversary of the Brussels terror attacks. Today’s attack is a reminder of the threat which is faced by all democratic societies. I understand a police officer has been injured by an attacker with a knife. This is a reminder of the debt of gratitude we owe to the police and the security services who risk their lives daily to protect us all. My thoughts are with all those who have been injured.”
