Libya has stopped jamming Arabic-language broadcasts of the British Broadcasting Corp., a spokesman for the BBC’s External Services said. “The jamming appears to have stopped,” he said of the interference traced to a site outside Tripoli. Libya began jamming the BBC’s Arabic Service in April, when Libyan troops fighting Chad government forces began to suffer heavy defeats. The BBC says its broadcasts in Polish are still being jammed from inside the Soviet Union, although Moscow--in a move linked to Soviet leader Mikhail S. Gorbachev’s liberalization program--stopped interfering with BBC’s Russian-language transmissions in January.
