Yemen army kills 2 tribesmen for pipeline blasts

The army's offensive in Marib province Sunday was aimed at intimidating militants who attacked a crude oil pipeline just half an hour after repairs to it were completed a day earlier, the official said.

An Electricity Ministry official says an attack on a power station was behind electricity outages in the capital Sanaa and other cities Sunday.

Some security officials suspect tribesmen allied with former longtime president, Ali Abdullah Saleh, of being behind the attacks in an attempt to undermine the new government.

All officials spoke on condition of anonymity because they were not authorized to release the information.
