Sri Lanka has refused entry to Sweden's Foreign Minister Carl Bildt. Mr Bildt was to have taken part in a European diplomatic mission. He is recalling Sweden's top diplomat in Sri Lanka for consultation.
The UK's David Miliband and France's Bernard Kouchner will still go on the mission, which is expected to push for a truce between the army and rebels.
Sri Lanka's foreign ministry said this was not a snub and it could only cope with so many high-level delegations.
