Regular shipping on the river Danube will not resume before the spring of 2002, following the removal of NATO bombing debris from the river in Serbia, the head of the Danube Commission, Hellmuth Strasser, said. The economies of countries using the lower Danube - mainly Romania, Bulgaria and Yugoslavia - are losing more than $306 million a year due to the obstruction of the river, he said. The Danube has been blocked along a vital stretch in Serbia since 1999, when NATO bombing destroyed three bridges at the city of Novi Sad. In April a Danish-Hungarian consortium was awarded a 26 million euro contract to begin cleaning debris from the river. Such cleaning, however, has yet to begin, Strasser said. - (Reuters)
