Welcome to our continuing coverage of unrest in Ukraine - a day after the deadliest clashes since anti-government protests began. At least 75 people were killed. Foreign ministers from Germany, France and Poland have been mediating crisis talks with President Viktor Yanukovych, who has announced that a deal has been reached to resolve the crisis. Neither the opposition nor the European foreign ministers have confirmed the announcement.
The signing of an agreement to resolve the crisis is expected at 12:00 (10:00 GMT), the presidential statement says. It says that no details of the agreement were given.
"It is a dark day for Europe when a government guns down its citizens," an editorial in The Times says. "The only slim consolation from the killing of two dozen demonstrators in Kiev is that it will speed the end of President Yanukovych."
The Interfax-Ukraine news agency says that there are up to 5,000 protesters in Kiev's Independence Square as of 05:20 local time on Friday morning while "no law enforcers have been spotted in the immediate vicinity of the barricades or in the streets adjacent to Independence Square". Protesters had been preparing tyres and petrol bombs and bringing them to the barricades all night, it says.
The Ukraine deal sees early elections, coalition, constitution change, AFP quoting TV reports says.
Mr Fabius has urged caution, Reuters reports, saying that the opposition needs more consultation time.
French news agency AFP quotes Foreign Minister Laurent Fabius as saying: "We cannot say anything definitive before the end of the morning" in relation to the possible signing of an agreement.
