The U.S. Department of Defense has published details of the U.S.-led coalition's latest strikes against the IS group in Iraq and Syria.
There was one strike in Syria, on an IS headquarters near the group's stronghold of Raqqa.
There were 19 strikes in Iraq including near Haditha, where there have been heavy clashes between IS and Iraqi security and tribal forces over the past three days. Eight strikes were carried out near Ramadi, where Iraqi forces have been clearing out IS militants after retaking the city center.
Back in Libya, Petroleum Facilities Guard fighters injured in clashes with IS militants near Sidra in Libya's oil crescent have been transferred to Misrata for medical treatment. The photos show them arriving in Misrata.
The Libya Observer tweeted this image earlier showing a list of 18 Petroleum Facilities Guard fighters injured in the clashes at Sidra on January 5.
At least 20 Syrian rebel commanders -- mostly hardline Islamists -- have died in targeted killings in Syria since December, according to activists, AFP reports.
No armed group has taken responsibility for the assassinations, whose targets include seven leading officers in Al-Qaeda's Syrian affiliate the Al Nusra Front. The most recent killing occurred today in Homs province: Abu Rateb al-Homsi, a local commander with the hardline Islamist Ahrar al-Sham group was killed.
According to Thomas Pierret, a Syria specialist at the University of Edinburgh, "the regime and its allies are by far the main suspects" in the killings.
"One of the components of the counter-insurgency strategy implemented by Russia since September is the decapitation of the insurgent leadership," he added.
With help from their Russian ally, intelligence services in Damascus have been able to gather better information on senior rebel figures, Pierret said.
More news of the aftermath of the deadly clashes between IS and Petroleum Facilities Guard fighters in Sidra -- as fears remain that IS is regrouping for another assault.
U.S. Army Col. Steve Warren tweets that Iraqi Counter Terrorism Service (CTS) are carrying out clearance operations to the east of Ramadi's city center and are encountering booby traps and pockets of resistance from IS militants remaining in the city.

U.S. Army Col. Steve Warren, the spokesman for the U.S.-led anti-IS coalition, has also commented in his press briefing today about the recent heavy clashes by IS militants near Haditha in Iraq's Anbar province.
Warren says that Iraqi Security Forces have repelled or regrouped and counterattacked against all IS advances near Haditha.
U.S. Army Col. Steve Warren -- spokesman for the U.S.-led anti-IS coalition -- has also commented on Operation Tidal Wave, the operation to target IS-controlled oil installations, which the group is using as a source of funding.
The spokesman for the U.S.-led coalition against IS says that around 2,500 IS militants were killed in U.S.-led air strikes in Iraq and Syria in December.
In the Iraqi city of Ramadi, recently retaken from the IS group, Sunni tribal fighters and local police will take over security duties from the Iraqi army and counter terrorism service, the spokesman for the U.S.-led coalition says.
