ISLAMABAD (Reuters) - - Pakistani Prime Minister Nawaz Sharif demanded to know on Thursday why police stood by while a pregnant woman was beaten to death by her family in front of one of the country's top courts.

Farzana Iqbal, 25, was killed by a group of attackers, including her father, on Tuesday because she had married the man she loved and prompted the anger of her family.
