Security around Kabul Tightened

Soviet forces in Kabul, the Afghan capital, have increased their patrols in and around the city and scores of new roadblocks have gone up on al roads leading out of town. All Westerners, including reporters and cameramen with passes issued by the Afghan Information Ministry, were turned back within an area of about 10 miles from Kabul, and foreigners trying to book passage on internal flights were refused tickets.

UPI correspondent Michael Keats reported from Kabul that armored personnel carriers and tanks from the 18,000 Soviet troops camped outside the capital clanked on patrol amid signs of a beefed-up Soviet security ring. The moves followed the shooting of at least two Soviet soldiers last week, the first confirmed attacks on the invaders inside snowbound Kabul.
