US warship reaches Georgian port

A US warship has arrived in the Georgian port of Batumi carrying the first delivery of aid supplies by sea.

Russian forces are still in control of the military port of Poti, to the north of Batumi, after Moscow withdrew most of its combat troops from the country.

French President Nicolas Sarkozy, who brokered the ceasefire, has urged Moscow to pull out those forces too, and called a summit of EU leaders.

Meanwhile, Georgia said a train full of fuel was blown up by a mine near Gori.

A huge plume of black smoke could be seen across the area and witnesses said the force of the blast had forced some of the train's wagons off the tracks.
