The United Nations officials have called on warring parties in Syria to facilitate immediate humanitarian and safe access to civilians trapped in the country by intense fighting.The head of the UN’s Children’s Fund (UNICEF) Anthony Lake on Friday called for an “immediate safe access” to people caught in the fighting. Lake said some 400,000 civilians are reportedly trapped in the city of Homs alone which has suffered some of the worst violence in Syria's 28-month-long conflict. He called on Syria’s government and the foreign-backed opposition to separate humanitarian issues from political agendas and to allow aid organizations to help the needy women and children in besieged areas. The head of the UNICEF also said the situation “is rapidly deteriorating” in Syria with reports of daily clashes and strikes that cause many casualties. The Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Valerie Amos also called on warring sides to allow access for aid organizations to get to people trapped in the fighting. On Thursday, the Russian Foreign Ministry said in a statement that Moscow dispatched another consignment of humanitarian aid worth $1.3 million to Syria in an effort to assist the victims of the unrest. Syria has been gripped by deadly unrest since 2011. According to UN Secretary General Ban Ki-moon, more than 100,000 people have been killed and a total of 7.8 million of others displaced since the outbreak of the violence.
