All police forces in the UK have reviewed security arrangements at upcoming public events following the Nice lorry attack, the Home Secretary has said.
Amber Rudd told the House of Commons that the Foreign Office was continuing to provide assistance to anyone concerned about friends or relatives caught up in the attack, in which 84 people were killed.
Ms Rudd said investigative assistance has been offered to French authorities following the incident, which she said defied "all comprehension".
French Prime Minister Manuel Valls faced boos and calls to resign as he laid a wreath for the 84 people killed in the lorry attack in Nice.
Hours later Mohamed Lahouaiej Bouhlel drove a 19-tonne lorry down the promenade killing 84 people and injuring 200 more.
France's prime minister stated on Sunday he believed the man behind the Nice lorry attack was radicalised "very quickly"
