JAN 2: A bank executive who said she witnessed Philippine President Joseph Estrada sign a bank account under a false name said today she feared for her life after a spate of deadly bomb attacks in Manila.Equitable PCI Bank senior vice-president Clarissa Ocampo told Estrada's corruption trial, which resumed Tuesday after a 11-day break, that she decided to testify against the President because she was "afraid of my life and the security of my family."Prosecution lawyers had earlier rushed to obtain her testimony in the belief this would afford her protection.However, asked at the Senate trial if she still feared for her life, she replies, ``Yes, of course, I do.''When asked why she was afraid, she said, ``because this is the government, this is Malacanang (the presidential palace).''``Especially after bombings, I was really very concerned,'' she said, referring to five almost-simultaneous bomb explosions across Manila on Saturday which killed at least 15 people and injured about 100 others.Opposition has charged that Estrada's allies were behind the bombing in an attempt to divert attention from the corruption trial.In turn, Estrada aides have said the blasts may have been intended to pressure the president into stepping down.
