HASSELT, Belgium — Two coal miners were killed and dozens wounded in a violent daylong clash with state police in Waterschei near here today [Jan. 31]. The first was killed by a bullet in the stomach as police stood off attacking miners, police said. The second was killed when police counterattacked.

Miners of the nearby Zwartberg coal pit went on strike last week to protest the scheduled closing of their mine later this year. It will throw hundreds of men out of work.

The demonstrations began at the pithead, where troopers tried to break up a protest meeting with tear-gas bombs. Two hundred punching and screaming miners broke through the troopers’ line. They marched south towards Winterslag, three miles away, where they were joined by several hundred other miners from another pit who stopped work out of sympathy. They shouted anti-government slogans as they tore up paving stones and hurled them at more troopers who appeared. They broke through a second tear-gas screen and beat up gendarmes who were throwing gas bombs.

The miners then turned towards Waterschei — the third village in the ‘‘black triangle’’ which produces much of Belgium’s coal. On the way, they tore up the railway from Heisden to Hasselt, knocked down electric pylons and overturned traffic lights. — New York Herald Tribune, European Edition, Feb. 1, 1966
