Pakistan president arrives home from Dubai

Pakistan\'s President Asif Ali Zardari arrived home from Dubai early Friday, officials said, against a backdrop of mounting tension and challenges to his government\'s precarious rule. A presidential official said Zardari, who spent more than a week in a Dubai hospital for treatment last month, returned in the early hours of Friday after a brief visit to attend a wedding. \"The President arrived at 5:00 am after attending a wedding in Dubai and he is in Islamabad now,\" Farhatullah Babar, Zardari\'s spokesman told AFP. The one-day trip came after a confrontation between Pakistan\'s civilian leaders and the military over a probe into the government\'s role in a scandal centred on a mysterious memo that sought US help in curbing the army\'s power.
