Things are certainly hotting up for foreign oil companies in Yemen. A blast shook an area near the headquarters of Canadian oil company Nexen in the capital Sanaa yesterday.

The blast followed Sunday’s mortar attack by an Al Qaeda terrorist organization on a residential complex in Yemen that houses executives and the headquarters of Safer E&P Operations Co.

Last week, the Jund al Yemen Brigades, an Al Qaeda affiliate group, also claimed responsibility for two operations carried out in Hadhramaut, including a bomb attack on a pipeline belonging to Total SA in the Sah Valley and mortar attack on an unidentified Chinese oil company operating in Al-Khish’a.

So the employees of the Safer E&P Company are probably not feeling that safe right now.
