Former House Speaker Newt Gingrich suggests sabotaging Iran's petro industry

The former speaker of the US House of Representatives has said that the US should "sabotage" Iran's oil and gas infrastructure as part of its efforts to bring down the government. In an interview with Al Jazeera's Avi Lewis for the Fault Lines programme, Republican Newt Gingrich said targeting Iran's refinery would spark an economic crisis that would destabilise the government in Tehran.
