U.S. Army Col. Steve Warren, the spokesman for the U.S.-led military operation against IS, is tweeting updates from a press conference.
Warren says that IS's raids near Haditha in Iraq's Anbar province have not been successful because the Iraqi Security Forces are stronger and because of air strikes from U.S.-led coalition.
Reuters has a few more details on Siddhartha Dhar, the London man believed to be the masked IS militant who appeared in a recent IS video showing the killing of five men.
Dhar, who is also known as Abu Rumaysah, is one of Britain's most high-profile Islamists and an associate of Anjem Choudary, Britain's best-known Islamist preacher who is due to go on trial next week accused of terrorism offenses.
A convert from Hinduism who lived in east London, Dhar regularly attended protests staged by the now banned organization al-Muhajiroun and had often spoken to the media in support of radical Islamic causes.
Libyan activist Ahmed El-Gasir has tweeted this map showing the locations of the clashes between IS militants and the Petroleum Facilities Guard (PFG) near the oil terminal of Sidra.
Saudi Arabia and Iran owe it to the international community to put aside their differences in the Middle East and focus on opposing the IS group, German Foreign Minister Frank-Walter Steinmeier told newspaper Bild, Reuters reports.
There is a "huge fire" in an oil storage tank in Libya's Sidra port as IS militants resume shelling, the National Oil Corp. says.
Reuters has more on the emerging reports that IS militants are attacking Libya's oil port of Sidra for the second day.
IS militants resumed shelling near Sidra and an oil storage tank in the port was hit, causing it to set on fire, according to Reuters, who are citing a Petroleum Facilities Guard spokesman and the National Oil Corporation.
The guards spokesman said the militants were 30-40 km (19-25 miles) from the port, which they also targeted on Monday in an attack that left seven guards dead and 25 wounded.
The IS group in Libya is "determined to seize oil fields/facilities in Libya," says the Atlantic Council's Mohamed Eljarh.
Amid reports that IS militants have resumed their attacks on Libya's oil terminals Sidra and Ras Lanuf today, it is worth recalling that the Petroleum Facilities Guard (PFG) -- set up in 2012 to protect Libya's oil installations -- asked Libya's internationally recognized government in August for more weapons to help it combat IS.
Exports of crude oil from Sidra and Ras Lanuf stopped in December 2014 when the state-run National Oil Corp. declared force majeure.
IS militants are attacking the Libyan oil terminals Sidra and Ras Lanuf and are reportedly shelling with rockets, according to sources in the Petroleum Facilities Guard (PFG).
