The Syrian regime has reached a new low — its death squads are using ambulances and hospitals to lure and kill wounded protesters. But Russia, Syria’s key backer and arms supplier, could bring an end to this carnage.

There are two governments that can influence Russia — Turkey and Germany — both of them support the Syrian democracy protesters and have strong ties with Russia. If we call on them to act now, they could weigh in behind mounting regional pressure and push Russian President Medvedev to stop propping up this brutal regime and help urgent global action.

Syria’s horror hospitals are the latest in a string of unspeakable crimes against peaceful protesters. So far, Russia has faced little condemnation for its complicity in these atrocities, but we can change that. Let’s build a massive petition to Merkel and Erdogan now to speak out and work with the Arab League to stop the brutality. Sign now, and share this with everyone — it will be delivered to their Foreign Ministries this week.

For months, Syria’s brutal President Assad has paid henchmen to wage war on his own people. Governments across the world have condemned these atrocities, but key European leaders could cut off the cash flow that finances this bloodbath.

Germany, France and Italy are the three main importers of Syrian oil. If they move to impose immediate EU sanctions, Assad’s slaughter funds will dry up. Assad has ignored political appeals for him to rein in his assault, and EU leaders have discussed ramping up sanctions, but only a massive global outcry will push them to act urgently.

We have no time to lose — every day dozens of Syrians are shot, tortured or disappeared simply for calling for basic democratic rights. The EU can stop subsidising it now. Sign the petition to EU heads of state to immediately adopt oil sanctions on Syria.
