Two powerful explosions in Albania's capital Tirana have gutted a business owned by the family of the country's interior minister and damaged the apartment of a senior police officer.

Authorities said no one was injured in the pre-dawn explosions Tuesday. Socialist Prime Minister Edi Rama described the incidents as a coordinated "act of terrorism."

Police say a third device was destroyed in central Tirana after they received a warning telephone call.

There was no immediate claim of responsibility for the explosions that occurred 25 minutes apart. The first destroyed a pharmacy owned by the family of Interior Minister Saimir Tahiri and shattered nearby windows.
