Two Swedes are suspected of having thrown hand grenades at Israel's embassy in Copenhagen in October last year.
One of the Swedes, a 20-year-old man, is also suspected of a murder in Malmö and has been requested to be extradited to Sweden, reports the Danish news agency Ritzau.
The murder is said to have taken place in August last year.
A hearing is being held today in the Copenhagen city court (district court) that will address the request for extradition to Sweden.
