"I have informed the [UN] Secretary General [Ban Ki-moon] and the Security Council…that a plan to reconvene here in Geneva the suspended Geneva intra-Syria talks on Monday the 7th of March on the assumption that there will not be any serious reasons to the contrary. The first phase of these talks will last for three weeks and then we will reassess the situation together with the Syrian parties," de Mistura said on Friday.
Earlier, de Mistura said he plans to resume the intra-Syria peace talks on March 7, provided that the ceasefire, which came into force on Saturday, holds.
De Mistura declined to say on Friday whether the Kurdish community would be represented at the next round of Syria peace talks.
"Let me elaborate on my plans after the 7th of March," the UN envoy said answering a question from a correspondent on Friday.
Syria has been mired in civil war since 2011, with government forces loyal to Syrian President Bashar Assad fighting against numerous opposition factions and extremist groups, such as Islamic State (ISIL), also known as Daesh, which is banned in a wide range of countries.
Talks between the Syrian government and representatives of the country's opposition factions began in Geneva on January 29. On February 3, de Mistura decided to postpone the talks as the parties were unable to reach a compromise on a number of issues. The opposition and government delegations blamed each other for the breakdown of the talks.
On February 22, Russia and the United States reached an agreement on the ceasefire in Syria. The ceasefire took effect at midnight on February 27, Damascus time. It does not apply to terrorist groups operating in the country.
