A powerful car bomb killed at least 27 people in Syria’s Idlib on Monday, as kidnappers freed four out of seven aid workers that were abducted Sunday.

A powerful car bomb killed at least 27 people in Syria's Idlib on Monday, a day after gunmen abducted seven Red Cross aid workers in the northwestern province.
  
The Syrian Observatory for Human Rights said the blast in the town of Darkush killed at least one child and that the death toll could rise because many of the wounded were in a serious condition. Activists said the blast targeted the market area of the town, which is a few kilometers (a couple of miles) from the border with Turkey, on the Orontes river.

Four of the kidnapped aid workers were meanwhile freed, International Committee of the Red Cross spokesman Ewan Watson said, adding the organization was awaiting further information about the others.

The ICRC has not commented on the nationality of those abducted, though it has said most of the group were Syrian. There has been no claim of responsibility.

Gunmen abducted Sunday seven International Committee of the Red Cross (ICRC) and Arab Red Crescent (SARC) staff in Idlib province.

The Red Cross said the team had travelled to Idlib on October 10 to assess the situation at health facilities and deliver aid.

"The convoy, which was on its way back to Damascus, was clearly marked with the ICRC emblem, which is not a religious symbol," it said.

But the ICRC said on Monday that it would not stop work in Syria despite the kidnapping. "We are completely committed to supporting the Syrian population in this difficult moment," ICRC spokesman Ewan Watson told Swiss public radio.

On the other hand, two cars laden with explosives and driven by suicide bombers blew up near the state broadcaster's headquarters at night in central Damascus, state media said, adding there were no casualties.

The blast  near the Umayyad Square caused only material damage to the wall of the General Establishment of Radio and Television, with no injuries reported.
A reporter for government television said that "there were some human remains at the scene, likely those of a suicide bomber".

A source estimated the amount of explosives used in each car at 100 kilograms, noting that one car was a Hyundai and the other a Honda.
