Aug 14 (Reuters) - Yemen's Houthis said they targeted an

Aramco facility in the Saudi city of Najran with a drone, the

group-run SABA news agency reported on Friday, citing a military

source.

The source said the attack was in response to what it

described as Saudi military aircraft violating Yemen's

sovereignty by entering airspace over the northeastern part of

Saada governorate.

There was no immediate confirmation from Saudi authorities

or Aramco. It was not immediately clear from the report whether

the facility was hit.
