The 47-year-old man shot his 18-year-old daughter for failing to give him water, and then killed his 16-year-old daughter when she tried to save her older sister, local police officer Mushtaq Warriach said.
The incident occurred Thursday evening near Sargodha, 300 km northeast of Multan, a main city in the eastern province of Punjab [ Images ].
Warriach said the man told police he "felt insulted" when his daughter remained seated after he asked her to get water.
The man was to appear before a judge later Friday, he said.
Violence against women is common in Pakistan, but such killings are rare.
