Saboteurs on Monday blew up an oil pipeline in southern Yemen that pumps crude oil to an export terminal on the Gulf of Aden, a security official said.
The attackers targeted the pipeline in the Al-Saeed area of Shabwa province, halting oil shipments from the Iyadh fields.
The pipeline, operated by a Korean firm, pumps 8,000 barrels per day to Al-Nashima, near the Balhaf terminal.

Impoverished Yemen produced an average of 170,000 bpd in 2011, down from an estimated 259,000 bpd in 2010, due to strikes, attacks on pipelines, and the evacuation of foreign staff, according to the Energy Information Administration.
The country's production dropped from 440,000 bpd in 2001, due to a lack of sufficient new investment in exploration and inadequate maintenance of facilities, according to the EIA.
Yemen exported 103,000 bpd in 2010, the EIA said.
Attacks on oil and gas pipelines in Yemen are frequent, and according to official figures, lost production due to the attacks cost the government more than $1 billion in 2012.
