Organisers are confident they have the security measures in place for the Cricket World Cup in England and Wales rated a "moderate" security risk.
Recent terror attacks in New Zealand and Sri Lanka have heightened safety concerns regarding the World Cup.
"When those incidents happened so close to the tournament, quite understandably that did cause some nervousness," Jill McCracken, the World Cup safety and security director, told reporters.

McCracken, explaining the security position regarding the World Cup, added: "The UK national threat level sits at 'severe', which means an attack is likely.
"But we also work with security services to assess the impact of the tournament itself and they have come to us with a bespoke threat for the event which is 'moderate' -- the second lowest on the scale of risk.
"The threat in the UK is always around crowded places, they look for mass casualties, but when you look at the security measures that we have around the venues, around the teams, and the background work we do, that actually reduces the threat."
Meanwhile, the ICC said there had been 3.2 million applications for tickets -- some four times the actual availability -- with 110,000 women and 100,000 Under-16s expected to attend.
