LAGOS, Dec. 1 (Xinhua) -- Nigerian President Umaru Yar'Adua will soon return from medical treatment in Saudi Arabia, local media reported on Tuesday.

The ruling People's Democratic Party (PDP) said in a statement carried by media that Yar'Adua would come back from Saudi Arabia, where he is being treated for acute pericarditis, an inflammatory condition of the coverings of the heart.

"Reports reaching us have it that the President is improving steadily and will soon returned to continue the good work he is doing," Rufai Alkali, the party's national publicity secretary, said in a statement.

He frowned on calls by some people on the president to either resign or be forced out by the members of the National Assembly.

The PDP, which also blamed opposition parties for what it called the tension being generated over the president's medical treatment abroad, wondered why they had failed to pray for him.

"The Peoples Democratic Party has observed with amazement the hype and tension being deliberately generated by so-called members of opposition parties over the medical check-up currently being undertaken by the President, Umaru Yar'Adua in a Saudi hospital," the statement said.

"We consider it particularly shocking that some Nigerians have chosen to over-sensationalize the situation and magnify it out of proportion in order to satisfy their selfish prejudices," it added.

"We pray for the safe return of the President and pray that the Almighty God touches the hearts of those peddling these rumors to repent from their evil ways," the party said.
