Syria ceasefire

Russia and Turkey had brokered a cessation of hostilities between the Syrian government and rebel groups.

Ahead of peace talks, rebels' representative says it's a 'real test of the power of Russia' to hold off Iran and the Syrian government.

Ankara said the moves threatened peace talks due to take place in Kazakhstan.

Fighters urge U.N. Security Council not to bless the truce if alleged violations by the government continue.

The ceasefire has to remain for peace talks to take place.

Putin said the Syrian government and opposition have signed a number of documents.

The battle of Aleppo, one of the worst of a civil war that has drawn in global and regional powers, has ended with victory for Syrian President Bashar al-Assad.

The Syrian army have made rapid gains against insurgents in the past two weeks and look closer than ever to restoring full control over Aleppo.

Putin's spokesman said militants are using the truce to regroup, rearm and attack.

In a last ditch effort to recover the ceasefire, U.S. Secretary of State John Kerry urged Russia and Syria to stop all flights over battle zones in Syria.

Chief Coordinator Hijab said the ceasefire deal arranged by the United States and Russia were flawed from the start.

Syrian army attacks rebel-held areas in Aleppo hours after ceasefire deal is announced.

Moscow also blamed al-Nusra for hostilities in three provinces.

Russian officials have accused the al-Nusra Front of preparing a push.

Both France and Russia have said that peace talks in Geneva must continue.

A U.S.-Russia brokered cessation of hostilities has been in place since Saturday.
