The price of shares in UK oil and gas company, BG Group have fallen by 15% following a warning that continuing unrest in Egypt is having an impact on production.
BG Group said it expects to produce between 590,000 and 630,000 barrels of oil per day in 2014, a fall of 5% compared with 2013.
It has issued a Force Majeure in Egypt, which informs investors of circumstances beyond the company's control.
The company said Egypt is using more gas than agreed for its domestic market, which is leaving less room for exports.
BG's chief executive Chris Finlayson said: "We face short-term issues which are reflected in our revised 2014 guidance. This is very disappointing,
"BG Group... will continue to negotiate with the Egyptian authorities and other stakeholders to seek a long term solution"
