Jerusalem: Israel on Tuesday said it had no evidence to back Syrian activists` claim that chemical weapons were used to attack rebels fighting to topple President Bashar al-Assad.
"We have seen reports from the opposition. It is not the first time. The opposition has an interest in drawing in international military intervention," Vice Prime Minister Moshe Yaalon said on Army Radio.
"As things stand now, we do not have any confirmation or proof that (chemical weapons) have already been used, but we are definitely following events with concern," he said.
The Syrian Observatory for Human Rights, based on activist accounts, said a poison gas could have been used in the city of Homs.
The Observatory, a British-based group with a network of activists across Syria, said those accounts spoke of six rebel fighters who died after inhaling smoke on the front line of Homs`s urban battleground. It said it could not confirm that poison gas had been used and called for an investigation.
The Syrian regime has stressed that it would never use chemical weapons.
