"Among other topics of the humanitarian group was the status of children affected by the conflict, homes for severely ill, bedridden children in the occupied territories whom Ukraine is ready to evacuate, but now it insists at least on access of UNICEF and ICRC to these institutions," she wrote on Facebook page on Wednesday after a meeting of the subgroup. The economic subgroup discussed the functioning of the Zolote checkpoint, which has been locked by Donbas militants. Former Ambassador of Ukraine to Moldova, Vice-President of the National Academy of Sciences Serhiy Pyrozhkov joined the work of the political subgroup, Gerashchenko said. But the issue of security was a major one, she said. "[Ukrainian representative Yevhen] Marchuk has provided compelling information about the critical increase in attacks and the violation of the ceasefire. No other issue could be resolved without addressing the issue of security. Therefore, the Ukrainian side has raised the issue of security with all the groups," she added.
