Islamabad, Dec 8 (IANS): Asif Ali Zardari who suddenly left the country for Dubai was "just undergoing tests", said his younger daughter on Twitter.
Aseefa B. Zardari tweeted: "The President is just undergoing tests, when cleared by doctors he will be released from hospital. Thank you for all the support."
Zardari abruptly flew out of Pakistan Tuesday, leading to much confusion and intense speculation. There were also rumours of a coup.
A US magazine quoted a former American official as saying that Zardari had a minor heart attack and may resign as president.
Zardari has three children - Aseefa, Bakhtawar and Bilawal.
