Jakarta  - Indonesia's defence minister accused Singapore of obstructing an extradition treaty because it fears it would have to hand over businessmen who sought refuge in the city-state with huge amounts of illegally gotten money, a news report said Friday.

Juwono Sudarsono also said a defence cooperation agreement with Singapore, negotiated simultaneously with the extradition pact, appeared to have collapsed as well, according to The Jakarta Post.

"They [the agreements] are frozen," Juwono told the Post.
