No one was hurt in the explosions, which occurred overnight in the "immediate proximity" to the Israeli embassy, police spokesman Jakob Hansen told reporters.

"Nobody was wounded and we are carrying out a preliminary investigation at the scene," police wrote on social media platform X earlier.

"It's too early to say if there is a link" between the blasts and the Israeli embassy, Hansen said.

The Israeli embassy is among several foreign missions, including Iran, Thailand, Turkey, and Romania, and is clustered in the upscale suburb of Hellerup, north of the Danish capital.

The blasts came as tensions in the Middle East are spiralling, with Iran firing a barrage of retaliatory missiles at Israeli territory and Israel vowing to make Iran "pay" for the barrage.
