The organisers of two major Saudi energy and investment conferences said their events will go ahead this month and reassured visitors on security, after missile attacks on Riyadh’s airport left four people dead and an airliner heavily damaged this week, Reuters reports.

Riyadh is sticking to plans to convene global events and trying to draw in investment even amid escalating war with the Houthis in Yemen that has seen the kingdom attacked dozens of times over the past weeks.

Organisers of the World Petroleum Congress, set to host top global oil executives and policymakers from Sunday to Thursday, said it would proceed as planned with foreign leaders and ministers in attendance, an email sent to delegates said.

“Your comfort is our priority,” it said, noting that alternative routes to Riyadh, including via a four-hour drive from Dammam on the kingdom’s eastern coast, were available.
