UN Secretary-General Ban Ki- moon on Friday condemned the Thursday bomb attack in Iran, which reportedly killed at least 20 people and wounded many others, Xinhua reported.
A statement issued here by the secretary-general's spokesperson said "The secretary-general condemns yesterday's bomb attack in a mosque in the Iranian city of Zahedan."
"He extends his heartfelt condolences to the government of the Islamic Republic of Iran and the families of the victims of this despicable act," the statement said.
The bomb went off on a holiday marking the anniversary of the death of Fatima, the daughter of the Prophet Mohammed, reports said.
Zahedan is the capital of Iran's Sistan-Baluchestan province and the city is close to the borders of both Pakistan and Afghanistan. Local Iranian police are often reportedly caught up in clashes with drugs smugglers and extremists.
