Tehran, May 13, IRNA -- Iranian Foreign Ministry Spokeswoman Marzieh Afkham strongly condemned the Wednesday terrorist attack on a religious minority group in the port city of Karachi, Southern Pakistan, that killed 43 people.

'Extremism and terrorism are inhumane and un-Islamic; killing of innocent people for any purpose and in any form is doomed and unjustified,' Afkham said on Wednesday.

She underlined that the main purpose of such terrorist acts is to harm the unity and integrity of the Pakistani society.

Afkham expressed confidence that stability and security in Pakistan would remain untouched through prudence and sympathy between the country's nation and government.

Afkham also extended her condolences to the Pakistani people and government as well as the bereaved families of the victims.

Gunmen riding on motorbikes attacked a bus carrying members of a religious minority in Karachi on Wednesday, killing 43 people and wounding 19 others, hospital officials said.

Six attackers used 9 mm pistols to shoot at the people on the bus, police said.

After the attack, the bus was driven into a hospital parking lot with bullet holes riddled all along its side, said Salma Wahid, an official at the Memon Medical Institute Hospital in Karachi.

Most of the people in the bus were unconscious and splattered with blood, she said.

The vehicle was carrying men, women and children from the Ismaili Muslim community, said Ahmed Chinoy, chairman of the Citizen Police Liaison Committee in Karachi, Pakistan's largest and most populous city.
