Saudis enforce no-go area in Yemen

Beirut: Saudi Arabia is using air power and artillery to enforce a 10km deep buffer zone inside Yemen to keep Yemeni rebels away from its southwestern border, a Saudi government adviser said on Thursday.

Saudi officials said heavy guns had pounded insurgent positions across the border yesterday to create what Saudi media have called a "kill zone".

The adviser, who asked not to be named, said the zone would be no place for civilians while the conflict raged. Any Yemeni caught crossing into Saudi Arabia would be interrogated to make sure no fighters were among them.

Saudi Arabia launched an offensive last week after rebels seized some Saudi territory.
