The European Union has imposed sanctions on two senior executives of Turkish Petroleum Corp (TPAO) over work by two drillships in the Eastern Mediterranean.

The EU labelled the pair as the key operatives of what it calls the company's “illegal” and “unauthorised” drilling activities.

The move targets TPAO vice president Mehmet Ferruh Akalin, who is also head of the company's exploration department, as well as the department's deputy director Ali Coscun Namoglu.
