The return of Russian humanitarian aid convoy is underway,

no major incidents or violations recorded

, the Head of the

OSCE

's mission in Rostov region Paul Picard told RIA Novosti, as trucks that have delivered humanitarian aid to eastern Ukraine are returning to Russia.

"There was nothing [no incidents]. The return process is underway," Picard said, adding that he could speak only about the situation at Russia's border checkpoint of Donetsk. "We cannot see beyond it as we have no authority and it is beyond out mandate," he noted.

On August 14, the trucks with Russian humanitarian aid arrived at the border, but Ukraine began customs clearance only on August 21. On Friday, the convoy crossed the border and

arrived in Luhansk

, the city struggling daily without regular food supplies, water, electricity and under constant shelling.

The Ukrainian Foreign Ministry described the convoy crossing the Russian border as a violation of international norms and urged its international partners to condemn the Russia's move.

Later, UN chief Ban Ki-moon

expressed

deep concern over the Russian aid convoy crossing the border into Ukraine.

Moscow

reminded

the UN that

Russia received a formal agreement from Kiev authorities for the passage of the humanitarian convoy through the Ukrainian border on August 12.

The humanitarian disaster in Luhansk, controlled by independence supporters, occurred after the Ukrainian army had blocked approaches to the city.
