For the first time a senior pro-Assad figure has been murdered in Lebanon.
Mohammad Darrar Jamo, a senior Syrian civil servant was shot 20 times at his home in a Shi’ite district in the south of the country at around two in the morning.
His wife said he had been contacted by the Baath party in Syria that same day warning him an attempt might be made on his life.
Eyewitnesses say three men were involved in the attack.
Elsewhere cross-border firing into the Turkish town of Ceylanpinar from Ras al-Ain, where Kurdish fighters are clashing with al-Qaeda-affiliated rebels, provoked a response from the Turkish army, which fired back. Two people were killed in Turkey by stray bullets.
South of the Syrian capital Damascus a car bomb claimed several civilian lives, including women and children.
As the fighting spreads the humanitarian situation worsens, and on Monday the UN warned that the situation in Syria was now “worse than Rwanda” during the conflict there.
