Bomb technicians deactivated on Monday two explosive devices planted on a natural gas pipeline in the south Russian republic of Ingushetia, a local security spokesman said.

Russian energy giant Gazrpom confirmed late on Sunday that a bomb had been found on the pipeline running from Mozdok in the Russian republic of North Ossetia to Georgia. Several gas transiting facilities were temporarily shut down over the news.

"Two explosive devices based on hand grenades have already been deactivated," the spokesman said.

He said sappers would continue searching for other explosives for several more hours.
