**Ailing Nigerian President Umaru Yar’Adua may have returned home secretly after three months’ medical treatment in Saudi Arabia, reports say.**A plane landed from Jeddah at the presidential wing of Abuja airport in the middle of the night, where an ambulance was waiting on the tarmac.
Earlier this month, Vice President Goodluck Jonathan became acting leader as fears mounted of a power vacuum.
Mr Yar’Adua had been suffering from a heart condition and kidney problems.
Reuters news agency quoted an unnamed government source as saying: “He just landed at Abuja airport on a Saudi plane escorted by the presidential plane. He is on his way to the [presidential] villa now.”
Soldiers were reported to be lining the main road from the airport to the city.
A delegation of Nigerian ministers had travelled to Saudi Arabia on Monday for an update on Mr Yar’Adua’s health.
They had been expected to report back to a weekly cabinet meeting on Wednesday.
