France has sent its senior human rights envoy to countries bordering Syria to collect evidence to level against the government in the International Criminal Court, according to diplomats.
Ambassador Francois Zimeray is "in the region" to collect testimony from Syrian refugees and from witnesses to the fighting in order that France can lodge a complaint with the court against Bashar al-Assad's government.
Paris hopes tangible and credible evidence of reportedly widespread abuses - including torture, murder and the shelling of civilian areas in revolt against the regime - will oblige the international community to act.
Syria is not a signatory to the treaty setting up the International Criminal Court, which was set up with UN support to prosecute genocide, war crimes and crimes against humanity where national courts fail to do so.
That being so, the only way the ICC could be charged with bringing a case against regime leaders would be by order of the UN Security Council.
That appears far off, as permanent council members Russia and China have prevented any condemnation of Assad's regime. Moscow is allied with Damascus and China traditionally opposes infringing national sovereignty.
French diplomats confirmed that Zimeray's mission was under way, but would not give details of his programme, seeking to protect his eventual contacts in the countries bordering Syria, in the grip of a year-long revolt.
The United Nations Commission for Human Rights has said it has also sent observers to the region to collect details on the regime's crackdown.
Officials in Paris said Britain and the European Union were thinking along the same lines, and that several non-governmental human rights groups were helping official bodies gather witness testimony and evidence.
Global watchdog Amnesty International said those arrested in Assad's brutal repression of the revolt face a "nightmarish world of systematic torture ... reminiscent of the dark era of the 1970s and 1980s."
