ISLAMABAD , Pakistan ( CNN ) -- Samina Rajput speaks in hushed tones about her husband , Asif , who was killed alongside former Pakistani Prime Minister Benazir Bhutto in the December 27 attack that convulsed the nation . Suicide bombings have killed 400 people and wounded nearly 1,000 others in the last three months . `` He always used to say ... ' I am ready to sacrifice my life for the party and my country , ' '' Rajput says . She clings to a weathered book with newspaper clippings of her husband , a 28-year-old Bhutto supporter who had great political ambitions . He wanted a brighter and freer Pakistan , Rajput says , as she turns the delicate pages of the scrapbook . The clippings on the faded pages offer little comfort .

CNN terrorism analyst Peter Bergen says the number of suicide bombings in Pakistan has `` reached unprecedented levels in the past year .

'' Pakistani President Pervez Musharraf has vowed to fight militancy and religious extremism , going after Taliban and al Qaeda within the country .

When he regained consciousness , he was missing his left eye and his right leg was severely injured . `` My leg was totally damaged , '' he says . `` My one left eye was damaged and I have several other injuries on my body . '' But at the time of the blast , Hamdani was not focused on his own pain , he says , because he was surrounded by the bodies of his dead friends lying in pools of blood . The bombings , he says , must be stopped . `` I hope that we will succeed and , God willing , we will try to stop these bloody cowards , '' he says . `` I do n't think they are Muslim . '' `` Innocent people are suffering . '' E-mail to a friend . CNN 's Wayne Drash contributed to this report .
