Pope John Paul II arrived in Madagascar Friday at the start of a four-nation African tour. His Alitalia Boeing 747 touched down at Antananarivo International Airport after a 10-hour flight from Rome. A "papal truce" has been declared on Madagascar to silence anti-government protests. The pope's nine-day trip will take him to the French Indian Ocean island of Reunion and to Zambia and Malawi. It is the 41st foreign pilgrimage of John Paul's 101/2-year papacy. In all, he will deliver 36 speeches and travel 13,500 miles. He is to return to Rome on May 6.
