Moscow, Sep 11 (IANS): The second Russian convoy loaded with humanitarian cargo for Ukraine's embattled eastern regions has been stuck at the Ukrainian border, the Russian emergency situations ministry said Thursday.

"The humanitarian aid still stays at the border near the town of Donetsk in Rostov region," Deputy Emergency Situations Minister Vladimir Stepanov said.

The aid delivery has been delayed because the Ukrainian side did not fulfill the preliminary plan coordinated with Russia three weeks ago, Stepanov said.

"We've been waiting for Kiev's response," Xinhua reported citing a Russian news agency as quoting him.

According to the official, the convoy carried about 2,000 tonnes of foods, medicine, water purification equipment, power generators and other consignment, which were donations coming from all Russian regions.

Sixteen representatives of the International Committee of the Red Cross have arrived in Rostov region to accompany the humanitarian mission.

The ministry said Sep 4 that Russia was ready to send a second batch of humanitarian aid to Ukraine pending Kiev's permission. The first convoy entered Ukraine's eastern Lugansk region Aug 22.

On Aug 29, Russian President Vladimir Putin agreed with Ukrainian President Petro Poroshenko on the proposal of delivering more humanitarian assistance to southeastern Ukraine by train.

Kiev and some Western countries have been opposing Russia's delivery of humanitarian aid for fear that Russia "might take the opportunity to invade Ukraine".
