СММ подтверждает, что минометный огонь ударил возле 2 автомобилей ОБСЕ сегодня на Ю. стороне моста в Луганск. СММ осуждает инцидент— СММ ОБСЄ в Україні (@OSCE_SMM) 26 июля 2015
"The Special Monitoring Mission confirms that mortar fire struck near two cars belonging to the OSCE today on the south side of the bridge leading to Lugansk. The Special Monitoring Mission condemns the incident."
A source familiar with the situation on the ground told Lugansk Information Center that "after the shelling by the Armed Forces of Ukraine stopped, Frisch decided to return to Lugansk."
LPR People's Militia also told the news hub that the OSCE representatives were forced to hide in dugouts and a sewer drainpipe over the course of two hours during the shelling. "Some of the [OSCE] observers, together with members of the People's Militia, took refuge in dugouts, with others taking cover in a sewer pipe in order to avoid being hit by shrapnel," a People's Militia source told Lugansk Information Center. The source added that the OSCE officials unsuccessfully attempted to call someone in a bid to stop the shelling.
The subgroups on political, economic, security and humanitarian issues were outlined in the Minsk ceasefire agreement worked out by the so-called Normandy quartet of Russia, Germany, France and Ukraine and signed by the parties to the Ukrainian conflict.
