Riyadh--Saudi Arabia's interior minister on Thursday ordered security measures strengthened along its borders and across the kingdom, including at oil facilities, as Riyadh led air strikes against Shiite rebels in neighbouring Yemen.
The minister, Prince Mohammed bin Nayef, vowed that the OPEC kingpin will "act firmly" against any attempts to undermine the kingdom's security, according to a statement published by the official SPA news agency.
