A speedboat and a tourist vessel have collided off the Greek island of Aegina, leaving at least three people dead and three others injured.

Greece's coast guard is conducting a search-and-rescue operation after the collision involving a tourist boat which was transporting people from Aegina in the Saronic Gulf near Athens to a beach on the nearby deserted islet of Moni.

There were believed to have been about 15 to 20 people onboard the tourist boat but it was unclear how many people were on the speedboat, the coast guard said.

The agency said a number of people were rescued and it was focusing on finding survivors.

Aegina's proximity to the Greek capital makes it a popular destination for Greeks and foreign tourists.
