WASHINGTON, D.C. (Al Jazeera): Politicians in the US have blocked a bill that would have made it harder for Syrian and Iraqi refugees to enter the country. The result of Wednesday’s vote was 55-43, with “yes” votes falling short of the 60 needed after Democrats refused to support the Republican-backed measure in the 100-member Senate. No Republicans voted against the bill, and only two Democrats backed it. Among other things, the bill would have required high-level US officials to verify that each refugee from Iraq and Syria posed no security risk before they were allowed into the US. Republicans had said tighter screening was essential to ensure the safety of Americans and prevent attacks.
