Syrian activists and an official with the Ahrar al-Sham ultraconservative Islamist rebel group say gunmen have shot and killed Abu Rateb al-Homsy, the group's leader in Homs province.
The Britain-based Syrian Observatory for Human Rights said that al-Homsy was killed when in a car with his wife in Farhaniyeh village.
Jihad researcher Kevin Jackson has tweeted more details from the biography of Abu al-Mughirah al-Qahtani, the now-dead leader of IS in Libya.
IS posted the biography, in Arabic, to the JustPaste.it site last night.
In it, Qahtani is praised as one of the founders of IS and the person who led its expansion in North Africa, Jackson tweets.
Qahtani was jailed twice, first in 2008.

IS has posted a biography of Abu al-Mughirah al-Qahtani, the late leader of the IS group in Libya.
The biography said that Qahtani joined the "jihadi caravan" -- i.e. began to wage jihad -- in 2003.
Qahtani is also said in the biography to have been in Abu Ghraib, the notorious prison outside Baghdad in Iraq.
Abas Aslani of Iran's Tasnim News Agency tweets that Iranian Deputy Foreign Minister Hossein Amir Abdollahian has talked on the phone with his Russian counterpart, Mikhail Bogdanov, regarding how to implement recent agreements on the Syrian conflict.
A video of the fires at the Sidra oil terminal following clashes with IS on January 5.
Reuters have tweeted this image of oil storage tanks on fire at Sidra following IS attacks on January 4 and 5.
Fires caused by clashes between IS militants and guards near Libya's biggest oil ports have spread to four oil storage tanks that were still burning today, Petroleum Facilities Guards spokesman Ali al-Hassi has said, Reuters is reporting.
There are three fires at Sidra and one at nearby Ras Lanuf which fire fighters are trying to control.
Hassi said that while the PFG are in control of Sidra and Ras Lanuf, skirmishes are continuing.
At least nine guards have been killed and more than 40 injured, while the PFG have recovered the bodies of 30 IS militants, according to Hassi.
IS has not launched a new attack (at least not yet) on Sidra in Libya today but this rather nice map tweeted earlier today by AFP shows Libya's oil facilities and where IS has attacked on January 4 and 5.
The IS group's local radio in its Libyan stronghold of Sirte is calling in militants to seize oil from unbelievers and playing jihadi "nasheeds" -- Arabic chants, Libyan analust Mohamed Eljarh says.
These updates come after a spokesman for Libya's Petroleum Facilities Guard said this morning that IS is trying to regroup some kilometers from Sidra.
