Ukraine tension: US troop reinforcements arrive near border

Hundreds of US paratroopers landed at a Polish airport near the Ukrainian border on Wednesday as part of a deployment of several thousand to bolster NATO's eastern flank amid tensions with Russia.

AFP reporters saw soldiers disembarking from two Boeing C-17 military transport planes and boarding buses at Rzeszow Airport, located around 100 kilometres (62 miles) from the border with Ukraine.

Soldiers were also transported on Black Hawk and Chinook helicopters to and from the airport.

Some of the soldiers brought working dogs on leads.

Armoured cars, military trucks, containers and dozens more soldiers were seen at a makeshift camp set up in and around a glass-covered conference centre opposite the airport terminal.

"We don't know yet," a sergeant manning a checkpoint into the camp, who declined to be named, told AFP when asked how long they might stay.
