Pakistan court probes president’s knowledge of memo to US that raised tensions with army

ISLAMABAD — Pakistan’s president Asif Ali zardari returned home Monday from medical treatment in Dubai, hours before the Supreme Court began a hearing on whether he knew of a secret memo to Washington that has raised tensions between the government and the military.

Asif Ali Zardari’s sudden departure on Dec. 6 was gleefully portrayed by his critics as the flight of a guilty man from the country, and there was feverish speculation about his health. But soon after his return, he was shown on state TV meeting members of his party, looking happy and healthy and apparently rebuffing rumors he was too ill to return to work.
