A powerful Pakistani governor shot and killed by one of his own guards was laid to rest on Wednesday under tight security.
Officials say the guard who shot Punjab Gov. Salman Taseer was angry about the politician's stance against the country's blasphemy law.
"Police are on maximum alert. Police are guarding all important installations in the city," Khusro Pervez, the commissioner of Lahore, said.
The law came under scrutiny in recent weeks when a Christian woman, Asia Bibi, was sentence to death for insulting Islam.
Taseer had visited Asia Bibi in jail and had called for her to be pardoned. He said that the blasphemy law should be amended.
The move angered many Islamic extremists, who made several threats against his life. A fatwa was also announced against him by Islamic religious leaders.
"I was under huge pressure to cow down before rightists on blasphemy," Taseer said in a Twitter message on Dec. 31. "Refused. Even if I'm the last man standing."
An aid to Pakistani President Zardari called Taseer "a courageous voice...on the rights of women and religious minorities in Pakistan.'
Officials say the bodyguard who shot Taseer was angry over his stance against the country's blasphemy law.
