Afghans living in the US have condemned Wednesday’s “deeply tragic” deadly shooting attack in Washington DC.   They have stressed that suspect Rahmanullah Lakanwal, who moved to the US from Afghanistan four years ago, does not represent them.   National Guard member Sarah Beckstrom, 20, was killed and a colleague, Andrew Wolfe, 24, is said to be fighting for his life.   In response, US President Donald Trump has halted the processing of all immigration requests from Afghans, ordered a review of green cards issued to individuals from 19 countries, and threatened a wider crackdown on migrants from what he calls “third-world countries”.   #WashingtonDC #BBCVerify #BBCNews
