The eyes of the world are on Syria as a ceasefire agreement continues to hold.
The Syrian government and rebels have signed up to deal brokered by the United States and Russia, despite concerns raised by rebels.
Hours before the ceasefire, Syrian President Bashar Assad said he is determined to recover all areas of the country from terrorist groups.
A nationwide ceasefire in Syria, brokered by the United States and Russia, has come into effect.
It is the second attempt this year by Washington and Moscow to bring an end to the five-year-long civil war.
Shortly before the week-long truce started, violence was reported in several areas throughout the country.
Under the terms of the deal, if it lasts for a week, Russia and America will co-ordinate attacks against some rebel groups including Islamic State and al-Qaeda's former Syria branch known as the Nusra Front.
The UN's special envoy to Syria said that Bashar Assad's government was preventing life-saving deliveries during a national ceasefire.
The US and Russia have agreed on a cessation of fighting in Syria from 12 September and hope Syrian sides resume diplomatic negotiations.
