A rebel-held town near Damascus was attacked by missiles and airstrikes sent by Syrian regime forces, resulting in the the deaths of at least 40 people.

In addition to the deaths, at least 200 people have been injured in Friday’s attack, according to the Wall Street Journal. The Syrian Observatory for Human Rights stated that government forces fired 12 missiles at the town of Douma, located 10 miles northeast of Damascus.

“Utterly heinous that while world leaders meet for peace in Vienna, attack(s) against civilians continue in Syria,” the Syrian Civil Defence said on Twitter.

Currently the numbers are still being added up as to how many people have been killed and injured due to Friday’s attack. Various news sources are reporting a variety of numbers at this time.

The attack came at the same time as 19 foreign ministers are meeting in Vienna to discuss the Syrian civil war, including the future of Syrian President Bashar Assad.

The Associated Press has reported that since the civil war started in March 2011, more than 250,000 people have been killed and up to one third of the population has been displaced.
