A Palestinian refugee was killed on Friday in clashes between Syrian regime forces and fighters from the Free Syrian Army, a Palestinian group said. Ahmad Rifay was shot dead during clashes in the city of Daraa, the Taskforce for Palestinians in Syria said in a statement. He lived in Daraa refugee camp. Several shells also landed in Yarmouk refugee camp in Damascus, causing material damage. No injuries have been reported. In Khan al-Sheik refugee camp southwest of Damascus, residents say Syrian forces have imposed a blockade on the camp, creating a severe humanitarian crisis due to a shortage in fuel and bread. Meanwhile, Syrian intelligence forces released two Palestinian refugees who had been detained for several months, the group added. Khalid Qawasmah from Handarat refugee camp and Amin Shawish from Raml refugee camp in Latakia were released on Friday by the Syrian regime. Husam Arisha, 26, from Yarmouk refugee camp has been in Syrian custody for almost eight months, while female activist Suad al-Tayyib was arrested for the second time on Friday, the group said.
