Like all readers, I was horrified by events in Tunisia on Friday, and spoke in the Commons statement on Monday to ask the PM what steps were being taken to step up training and support to security forces in other countries where British citizens might be under threat.

What happened on Friday was an act of unspeakable evil, formulated to inflict maximum pain on innocent people doing nothing more than enjoying what should have been a relaxing holiday with family or friends.

The loss of innocent life, with people targeted for no reason other than being holiday-makers, is truly appalling. Seeing in newspaper and TV reports the faces of those who were so senselessly murdered – from Wales, England, Scotland, Ireland; happy couples, young people, three generations from one family – is just heart-breaking.

One can only imagine the pain of those bereaved, the trauma and terror of those who survived but witnessed the events, and the devastation for the local people drawn into such horror.

Stories of bravery and heroism have emerged; of people, both holiday-makers and locals, putting their own lives in danger to save others - and their bravery shines through, in contrast to the cowardice of an attacker who targeted unsuspecting and defenceless people in such brutal fashion.

There were terror attacks in France and Kuwait on the same day – not directly linked it would seem, but certainly all carried out in support of and with encouragement from Da'esh (a more accurate name for the barbarous organisation formerly known as ISIL or ISIS, given it is neither Islamic nor a State).

Like the brutal racist attack on churchgoers in Charleston the week before, people who commit such acts of barbarism represent the very worst of human nature and capacity for evil and violence - and certainly not any faith or higher calling.

We must do all we can - locally, nationally and internationally – to fight this. I say locally because of course we’ve seen reports of young and impressionable individuals from this constituency who have been radicalised by people offering false promises and a twisted version of Islam. Local faith leaders across the board, including from the Muslim community, have rightly condemned these activities and the driving ideology.

In the face of this and other acts of terrorism, we may feel helpless. But we must not allow extremists to win. We must continue to ensure our security services are empowered to keep us safe; we must challenge terror organisations at their roots and in their finances; and ultimately challenge those at every level who preach hate and oppression - from whatever community, faith or denomination they come.
