First Minister Carwyn Jones has described a suspected terror attack at Westminster as "a terrible attack at the heart of our democracy."
Four people were killed and dozens more were injured after a car and knife attack in London on Wednesday afternoon.
The mother of Westminster attacker, Khalid Masood, has spoken of her shock over her son's actions.

Khalid Masood, who was born Adrian Ajao, used a vehicle to mow down pedestrians on Westminster Bridge last Wednesday.
PC Keith Palmer also died during the attack.
A police presence remains at the rural Carmarthenshire home of terrorist Khalid Masood's mother on Friday evening.
Labour MP Chris Bryant described PC Palmer as 'our shield and defender yesterday.'
