The Tihange power plant, an hour's drive from the Belgian capital in the province of Liege, and the Doel power plant in Antwerp have been cleared amid heightened fears of another attack. Security has been stepped up at both Doel, which houses four reactors, and Tihange, which houses three. Armed police and the Belgian military have been on site since the weekend following growing calls from the energy industry to beef up security at the potentially vulnerable plants. . . .
