Shared commitment critical to counter threat of terrorism

Monday's suicide bombing in the British city of Manchester, which killed 22 people, including children, was the most serious terrorist attack in the country since 2005.

The Islamic State, a terrorist group still wreaking havoc in Iraq and Syria, claimed responsibility, while the British police named the attacker as 22-year-old Salman Abedi, born in Manchester to Libyan parents, who died after setting off an improvised explosive device.

That a number of European cities have suffered terrorist attacks in recent years should be a reminder that security can never be emphasized enough. The fact that the deadly bombing in Manchester targeted a concert by the popular US singer Ariana Grande also shows the importance of buttressing up security in large sites and venues.
