Around 50 senior members of Ahrar al Sham, an Islamist rebel group in Syria have been killed or wounded by an explosion in the northwest of the country. The group's commander Hassan Aboud was among the dead as Jim Muir reports.
The Islamic Front, the umbrella group in which the Ahrar al Sham are the strongest faction, said that Hassan Aboud was among at least a dozen leading figures it named as having died in the explosion at the headquarters in the town of Romhamdan in Idlib Province while a big meeting was under way. The final number of people who died is expected to be much higher. Although the group is hard line Islamist in orientation, it has opposed and clashed with the ultra radical Islamic State (IS) which is the most likely quarter to be blamed for the attack as it was when another Ahrar al Sham leader Abu Hada Masuri was killed in a suicide bomber attack on his headquarters in Aleppo in February.
The World Health Organization has reported another sharp rise in the number of people killed by the Ebola virus in West Africa. The WHO said 2,296 victims have died, half of them within the past three weeks.

The situation here is really bad. It is completely out of control and we foresee and need at least 1,000 beds. We have in totally in Monrovia about 240 beds. That means that meantimes people who have come to here we have to tell them to turn them away. They come back home, they are still sick people. They can in fact die in their home. And so it is a literally bad way for the disease to spread.
