Khaled al-Khaled, whose 16-year-old son is struggling to recover from the attack, said he rejects foreign intervention in Syria, but that "the regime has forced us to join hands with enemies". "The United States has to ask itself a question: How angry do we want to be on this issue?"

The victims of Tuesday's chemical attack in the northern town of Khan Sheikhoun, which killed more than 80 people and wounded dozens more, welcomed the strike, but said they feared it would be a one-off.
