Russia's Defense Ministry is tweeting about its air strikes in Syria. The ministry says that it is working with "partners" to obtain credible intelligence about targets.
The ministry also says that it only carries out strikes after eliminating risks of harm to civilians. Opposition groups, NGOs including Medicins Sans Frontieres and activist groups have said that Russian air strikes have led to a high number of civilian casualties.

Russia ready to discuss Syria cease fire: Deputy FM
Russia is ready to discuss the issue of a cease fire in Syria at the Munich conference from Feb. 12-14, deputy foreign minister Gennady Gatilov has said.
"We are going toward this. We are ready to discuss the question of the modalities of a cease fire," Gatilov told reporters, commenting on media reports that Russia had proposed a cease fire from March 1.
However, Washington officials speaking anonymously have said that a March 1 ceasefire proposal reportedly sent by Russia to the United States was an attempt by Russia to give itself and the Syrian government three more weeks to crush moderate rebel groups.
IS video appears to show four-year-old British child blowing up 'spies'
A grisly new IS killing video appears to show a British child being made to blow up three hostages whom IS alleged were British spies.
The child in the video looks like Isa Dare, a four-year-old boy whose mother Grace Dare has joined the IS group in Syria.
The boy is shown appearing to press a button on a detonator after which a car containing three IS hostages explodes.
Before he presses the detonator, the child is filmed shouting about "infidels" and pointing his finger before the three orange-clad prisoners are shown tied up in the car.
Before the execution-style killing the three prisoners are filmed giving "confessions" about being spies.
An adult IS militant with a British accent gives a speech addressed to the British Prime Minister David Cameron, in which he says that the hostages in the car are spies.
"Firstly, when you sent your spies to Syria and when you authorized for your men, thousands of miles away, to push a button to kill our brothers who lived in the West," the militant says, according to The Independent.
"So today, we're going to kill your spies the same way they helped you kill our brothers"
The adult militant then gestures to the child, who presses the button on the detonator.
Isa Dare has appeared in a previous IS killing video last month in which he talked of killing non-believers. His grandfather, Henry Dare, recognized the child as his grandson.
Isa's mother, Grace Dare, who is a convert to Islam and was radicalized in London tweeted in 2014 that she wanted to become the first woman to "kill a UK or US terrorist."

Tara Nettleton, widow of notorious Australian IS militant, dies in Syria
Tara Nettleton, the widow of Australian IS militant Khaled Sharrouf, has died in Syria, the Australian press is reporting.
Nettleton, also an Australian, is thought to have died some time ago from complications from appendicitis, after she was not able to access life-saving health services.
She is thought to have been living in IS's Syrian stronghold of Raqqa with her four children and one grandchild.
Nettleton's husband Sharrouf is believed to have died last year. Initial reports said that he was killed in an air strike in June, but later evidence suggested he was killed some time later in July.
Sharrouf became notorious after he tweeted a photo of his son holding the severed head of a Syrian soldier.
It is believed that Sharrouf married Tara's eldest daughter Zaynab to an IS militant Mohammed Elomar, who was killed in June.
British man jailed after going to Syria to fight alongside IS
A 29-year-old British man has been jailed for seven years after traveling to Syria to fight alongside the IS group.
Mohammed Uddin traveled to Syria in November 2014 with the intention of joining IS and fighting alongside the extremist group, a South East Counter Terrorism spokesman said.
Uddin crossed back into Turkey just over a month later, in December 2014, but was arrested in Gaziantep.
The Telegraph's Louisa Loveluck has spoken with Syrian refugees and aid workers at the Kilis border crossing in Turkey, where people have fled fighting in Syria's Aleppo province.

Hijab, who spoke after a meeting with British Foreign Secretary Philip Hammond, added that the opposition wants aid to be let through to civilians.
