Qatar may raise its stake in Hochtief beyond 9.1 percent, German daily Financial Times Deutschland said without quoting sources.

The emirate may buy additional shares over the stock market to ensure that construction projects currently underway in Qatar are not disrupted, the paper said.   

Earlier this week Qatar said it will buy a 9.1 percent stake in Hochtief for 400 million euros, adding muscle to the No.1 German builder's fight against a hostile takeover approach from Spanish rival ACS.- Reuters
