This morning the humanitarian corridor for Mariupol started working, the Deputy Prime Minister of Ukraine Iryna Vereshchuk said.

At the same time, a humanitarian cargo left Zaporizhzhya in the direction of Mariupol, which consists of eight trucks, as well as more than 30 buses to pick up people and the elderly on the way back.

"The cargo consists of water, medicine, basic cereals and other products that will help people survive. The weight of the cargo is more than 90 tons," the minister specified.

Ukraine is counting on the commitments that Russia has made by officially warning the Red Cross that it is ready to observe the cease-fire, Vereshchuk said.

"However, now there are signals that the Russian Federation is shelling the direction of the humanitarian cargo.

If the shelling continues, and if it harms the lives and health of civilians in the humanitarian corridor - we will immediately appeal to the International Tribunal to bring to justice those who made the decision and did not fulfill the promises they made," she assured.

The deputy prime minister urged the leaders of other countries to monitor the situation along the way.

"We appeal to all the leaders of the free world to monitor the situation that is unfolding in the Mariupol direction, where literally 300 thousand people have been held hostage. Among them are insulin-dependent, cancer patients, young children. Therefore, this is a humanitarian disaster that requires the attention of the whole world," she said.
