Syria's White Helmets have sent their condolences to the family of veteran Senator John McCain, who passed away on Saturday after a year-long battle with brain cancer.The civil rescue team, which have saved tens thousands of lives following regime bombing, praised McCain for his support for the Syrian revolution and constant opposition to Bashar al-Assad's regime."We are profoundly saddened by the death of Senator John McCain, an extraordinary man and politician, and a staunch supporter of peace, human rights and dignity for all, in his country, in Syria and everywhere," the civil rescue team said in a statement."McCain was a man who believed firmly in international law and human rights, which is why is invariably went the extra mile to support the White Helmets in our work to save lives," the group added."His unwavering values and principles and his tireless work for the oppressed and vulnerable live on and will continue guiding our actions as humanitarians and human rights defenders."The Republican senator passed away on Saturday at his home in Arizona surrounded by his family, with the White Helmets offering McCain's family their "sincere and heartfelt condolences" on Tuesday.McCain was one of the US' Senate's most vocal supporters of the Syrian opposition, clashing with President Donald Trump several times on the issue.Following the fatal chemical attack on the opposition enclave of Eastern Ghouta in April, McCain called out Trump for announcing that the US was withdrawing from Syria.He saw this as a signal to Bashar al-Assad's brutal regime that Washington was unconcerned with the Syria civil war, thus giving Assad a green light to use chemical weapons , again.He called for Trump to take tough action against the Syrian regime for the chemical massacre, but appeared disappointed with the limited scale of the US strikes.McCain also condemned President Barack Obama's inaction during his tenure in office, which many viewed as contributing to the Syrian regime's escalation of bombing and other attacks on civilian areas.When McCain's death was announced, Syrians took to social media to mourn the death of the US politician who many viewed as a lone supporter of their cause in the Senate.
