Reneem Hezabar, a financial consultant with Middle East Consulting Solutions in Gaziantep, Turkey, expects a phone call any day now with the news that her father has been killed. He is one of the few doctors working in her native city of Idlib in northwest Syria, and the Russian-Syrian alliance has been bombing hospitals in the province, the last stronghold of Syria’s revolution, since the latest offensive began April 28.

The Syrian American Medical Society, one of the few remaining medical relief organizations working on the ground in Syria, said there have been 25 attacks on health facilities, “each of which represents an egregious violation of international humanitarian law.” The Syrian government said it is only targeting the extremist militant group, Hayat Tahrir al-Sham, which, since January, has strengthened its control across the province and in northern Hama, holding most of the region today. The regime has been using a cocktail of arms, including incendiary weapons, cluster munitions and barrel bombs.

The Syrian Observatory for Human Rights said the latest offensive has killed 408 civilians and displaced over 300,000, the greatest amount of displaced people since the start of the conflict, with half of the civilians being displaced for at least a second time. In a press statement released June 11, medical society President Ahmad Tarakji said: “The situation in Idlib continues to worsen by the day, yet the international community remains silent, or unwilling, to act to protect these vulnerable civilians.”

Physicians for Human Rights said that bombing health facilities is part of a broader strategy aimed at “achieving military gains through the collective punishment of civilians, regardless of the human toll.”
