Air strikes on the Syrian city of Idlib killed and injured more than 150 people on Monday evening, the Syrian Observatory for Human Rights said. 

The planes that struck the opposition-held city were believed to be Russian.

Meanwhile, a surprise assault by the ISIL trapped tens of thousands of terrified people on the Syrian border with Turkey, Doctors Without Borders said Monday, warning the situation was "unacceptable".

Pablo Marco, the regional manager of the charity known by its French acronym MSF, said concerns were rising for a large civilian population less than five kilometers (three miles) from advancing ISIL extremists.

"We are talking about 100,000 people who are trapped a few kilometers from ISIL. They are terrified, there is nowhere to go," Marco said.

The Local Coordination Committees, an activist network, said 10 people were killed when the city’s National Hospital was hit, but had no details about casualties elsewhere in the city.

The opposition Civil Defense, which carries out rescue operations, gave a much higher casualty figure, saying dozens were killed and hundreds wounded in the air strikes in which several hospitals were damaged. The group said it had deployed its entire Idlib corps to take part in rescue operations.
