Over 100 tons of uncollected garbage have been left to stack up in Hanoi's Nam Tu Liem District after sanitation workers went on strike. 

Garbage lies stacked up behind My Dinh coach station in Nam Tu Liem District.

Over the past six days, employees of Nam Hanoi Group JSC, responsible for collecting rubbish in the district, went on strike after the company failed to win a new contract and pay them on time, said Nguyen Duc Hiep, deputy director of the district's construction investment project management board, adding a large number of trash carts have been damaged in the process.

Hiep confirmed the company's contract would end Thursday and that garbage in the district would be collected by the Urenco Cau Dien branch under Hanoi Urban Environment Company (Urenco 7).

Dozens of trash-filled carts inundate Ham Nghi Street during rush hour.

On Ton That Thuyet Street, garbage carts are covered with canvas to reduce the stink.

Carts overloaded with garbage nearly two meters high on Nguyen Hoang Street at 7 a.m. on Wednesday.
