The fresh ceasefire in eastern Ukraine has reduced violence in the conflict-hit area, the Organization for Security and Cooperation in Europe (OSCE) said on Thursday.

"The recommitment to the ceasefire has brought a result -- less violence," Alexander Hug, first deputy chief monitor of the OSCE special monitoring mission to Ukraine, told reporters.

In the past week, OSCE monitors have documented some 1,200 cases of ceasefire violations, down 85 percent compared with a week before, Hug said.

According to preliminary information, for the first time in weeks, there were no civilian casualties in the conflict-hit region in the past seven days, he added.

On June 27, the Trilateral Contact Group on Donbas crisis reached an agreement on a fresh round of ceasefire in the region starting about midnight on July 1.

The Trilateral Contact Group is a group of representatives from Ukraine, Russia and the OSCE that was formed as an instrument to facilitate a diplomatic resolution to the conflict.
