By Angeliki Koutantou ATHENS (Reuters) - Talks between Greece and its international creditors over a new bailout package will be delayed by a couple of days because of organisational issues, a finance ministry official said on Saturday. The meetings with officials from the European Commission, European Central Bank and International Monetary Fund were supposed to start on Monday after being delayed for issues including the location of talks and security last week. A finance ministry official, who declined to be named, said talks between the technical teams of the lenders will start on Tuesday, while the mission chiefs will arrive in Athens with a delay of a couple of days for technical reasons.
