Pakistan's southern port of Karachi has been subjected to two days of incessant rain, and power has still not been restored in many areas.
Residents furious about rain-related deaths and power failures came out to demonstrate in various part of the city and blocked the main highway out of the city for several hours on Sunday night.
Witnesses say that police fired their guns into the air to disperse the protesters.

Bangladesh is one of the world's wettest countries and usually suffers heavy flooding, but this year's annual monsoon rains are much weaker than normal.
The BBC's Mark Dummett in Dhaka says the situation is a source of anxiety for farmers and government officials. The authorities say that there has been been 40% less rain this year than normal.
The government is concerned that this could have a seriously adverse affect on the next food harvest.
An official in the northern town of Dinajpur said that much farmland there was now bone-dry, so was completely useless for planting rice.
