Syria has reportedly agreed to open more land routes from Turkey to allow for the delivery of humanitarian aid by the United Nations to earthquake victims in the opposition-controlled northwestern part of the country.

Syrian President Bashar al-Assad met with UN emergency relief coordinator Martin Griffiths in Damascus on Monday.

Griffiths informed the UN Security Council in an emergency online meeting that Assad agreed to open two more border crossings for three months.

The decision comes a week after a magnitude 7.8 earthquake jolted Turkey and Syria, causing catastrophic damage and killing more than 35,000 people.

Under the current Security Council mandate, only one crossing is open for the delivery of food, medical supplies and other goods to the opposition-controlled region in the country's northwest.

UN Secretary-General Antonio Guterres said in a statement on Monday that opening the additional crossing points "will allow more aid to go in, faster."
