Turkey rescuers report noises beneath the debris.

(CNN) ⸻ Rescuers in southern Turkey are still hearing voices from under the rubble of a 7.8 magnitude earthquake, offering a glimmer of hope of finding more survivors. Eight days after the tremor and its violent aftershocks, more than 37,800 people have been confirmed dead across Turkey and Syria. UN workers are racing to funnel aid to survivors in Syria through two new border crossings approved by the government in Damascus. The UN is launching a $397 million humanitarian appeal for victims of the earthquake in Syria for three months and finalizing a similar appeal for survivors in Turkey. International aid has been slow to arrive in rebel-held areas in northern and northwestern Syria due to years of conflict and an existing humanitarian crisis. Syrian Foreign Minister Faisal Mekdad said last week that any aid must go through Damascus, but Western nations have been reluctant to lift sanctions. On Tuesday, a Saudi Arabian plane carrying 35 tons of food, medical aid and shelter landed at Aleppo International Airport, the first shipment of aid from the kingdom to government-held territory since the February 6 earthquake. Turkey's Vice President Fuat Oktay denied reports of food and aid shortages, and more than 9,200 foreign personnel are taking part in the country's search and rescue operations. On Monday, UN aid chief Martin Griffiths said the rescue phase of the response was "coming to a close". The World Health Organization (WHO) has stressed the need to "focus on trauma rehabilitation" when treating populations stricken by the devastating disaster in Turkey. The WHO's Turkey Representative Batyr Berdyklychev highlighted the "growing problem" of a "traumatized population" and the need for psychological and mental health services in the affected regions. The WHO is negotiating with Turkish authorities to make sure quake survivors can access mental health services. WHO Regional Director for Europe Hans Kluge told the briefing that the "immediate priority" for the 22 emergency medical teams deployed by the WHO to Turkey is "working particularly to deal with the high number of trauma patients and catastrophic injuries."
