KARACHI - Five people were injured on Sunday when Muslims protesting against a video that ridicules the Prophet Mohammad clashed with police in trying to reach the US consulate in Karachi, Pakistan's largest city.

Several groups had called for the protests in Pakistan on Sunday.

In Karachi, around 1,000 protesters began throwing stones and police responded with teargas and by firing into the air, said senior policeman Fayyaz Laghari. Two policemen and three protesters were injured.

Around 4,000 people demonstrated in the eastern city of Lahore and about same number in Kirri Shamozai in the north.

Local television stations aired footage of other small, peaceful protests in more than a dozen towns and cities.
