Not Ukraine related but still...
So the truce has now officially come into force:
A cease-fire has come into force in eastern Ukraine after almost five months of fighting.
Earlier on September 5 in the Belarusian capital, Minsk, Ukrainian officials and pro-Russian separatists agreed to stop firing at 1800 local time (eds. 1700 Prague time).
Ukrainian President Petro Poroshenko said he would do "everything possible and impossible" to end the bloodshed.
A top separatist leader said the truce doesn’t changed the rebels’ policy of advocating separation from Ukraine.
The Minsk talks follow a telephone conversation between Poroshenko and Russian President Vladimir Putin on September 3 in which they discussed ways to end the conflict that has killed more than 2,600 people in eastern Ukraine since April.
Fierce fighting was reported at the Donetsk international airport and outside the southeastern port city of Mariupol ahead of the cease-fire agreement.
More on this developing story from Estonia:
Russian Ambassador to Estonia Yury Merzlakov has been summoned to the Estonian Foreign Ministry for an explanation after Estonia said one of its security police officers had been abducted at gunpoint in Estonia and taken to Russia.
Estonia's Internal Security Service said the incident occurred at about 9 a.m. near the Luhamaa border post, and started with the jamming of communications and the setting off of a smoke grenade.
Arnold Sinsalu, Estonian Internal Security Agency's general director, said there were signs of a violent struggle but no indication of a firefight.
A criminal case has been opened on charges of abduction and illegal border crossing.
The incident comes two days after U.S. President Barack Obama spoke in Tallinn and pledged that NATO allies would always come to the defense of Estonia under Article 5 of the alliance's charter.
In April, our correspondent went to Estonia and wrote about the country's ethnic Russian population.
A rare anti-war protest in Russia, reported by our Russian Service:
BRYANSK, Russia -- Soviet-Afghan war veterans in Russia's western city of Bryansk held a picket protesting Russian involvement in the military conflict in Ukraine.
About a dozen members of the local Union of Afghan War veterans held placards saying "No to War in Ukraine!" and "No To A Second Afghanistan!"
A leader of the union, Vladimir Barabanov, who served in Afghanistan from 1986 to 1988, told RFE/RL that the second public protest against the war in Ukraine will be held in Bryansk on September 13 in the form of a public gathering for people to express their views.
Both public actions have been officially approved by local authorities.
Barabanov said Russia's Union of Afghan War Veterans does not support his regional union's viewpoint.
Obama is speaking soon at the NATO conference:
BREAKING: U.S. President Barack Obama says he is "confident" about the creation of a broad international coalition to counter Islamic State militants and said they will ultimately be "defeated."
