Two people were killed and another was injured in an armed attack on a Moscow slot machine arcade early Thursday morning, in what has become the tenth such robbery in the city since the start of the year.

Armed men burst into the north Moscow arcade at about 6 a.m. and opened fire, the Interfax news agency reported. They killed a security guard and a customer, and seriously wounded the cashier.

The assailants took the cash from the slot and game machines before fleeing the scene.

Video and slot machine arcades have become extremely common all over Moscow, where gambling is legal. They are located next to virtually every metro station and stand out with their bright lights. The fact that they are often housed in quickly-erected kiosks makes them an easy target.
