A 25-year-old man was critically injured in a head-on collision between his car and a minibus on the Mellieħa bypass in the late afternoon yesterday.
The police said a British family, including two girls aged six and 10, and the minibus driver were also injured and hospitalised.
In another accident earlier, this time on the Birkirkara bypass involving three cars, a 33-year-old pregnant woman was taken to hospital for observation.
The woman was a passenger in a Mitsubishi Pajero.
The other cars were a Toyota and a Volkswagen Golf which ended up on its side, blocking the road for some time.
