Two rescuers were among eight civilians killed in Russian and Syrian regime airstrikes in the north-western province of Idlib on Wednesday (June 26th), AFP reported.
The two civil defence workers, known as the White Helmets, were killed after Russian airstrikes hit their ambulance in Khan Sheikhun, the Syrian Observatory for Human Rights said.
The rescue group said a "double-tap attack" by Russian warplanes had "targeted" rescue workers repeatedly as they were evacuating injured civilians from the town.
Five other volunteers also were wounded, the group said.
The latest attack came nearly one week after regime airstrikes on an ambulance in the town of Maarat al-Numan killed three rescue workers.
"The world continues to fail to protect us and other humanitarian workers," the group said in a statement on social media.
Six other civilians were killed Wednesday in a series of regime airstrikes on several parts of the Idlib region, the Observatory said.
One more civilian succumbed to wounds sustained days ago during regime airstrikes on Khan Sheikhun, it said.
