Ten events most likely to hit the headlines in 2018

9. Domestic worries: Gun violence in the US

A horrifying shooting incident happened at a music festival on Oct 1 outside a Las Vegas casino, , causing 59 deaths and 527 injuries. The US lowered the flag to half-mast to mourn the victims after the incident.

The incident triggered another discussion on gun control, which remains a thorny issue in the US. The Second Amendment of the US Constitution, NRA lobbying, the growth of homegrown terrorism and a president who advocates gun ownership rights all play roles in the debate.
