UNITED NATIONS -- UN Secretary-General Ban Ki-moon on Tuesday condemned a deadly terrorist attack in Egypt that has left at least 14 dead and more than 100 others wounded.

In a statement issued here by his spokesperson, Ban expressed serious concern at the recent developments in Egypt and called on Egyptians to "find common ground and renewed consensus around the country's transition."

At least 14 people were killed and 130 others wounded early Tuesday as a powerful explosion ripped through local police headquarters in Egypt's Nile Delta city of Mansoura.

Tensions have been running high in the African country since the fall of former Islamist President Mohamed Morsi in early July, with a string of bomb attacks taking place across the country.

In Tuesday's statement, Ban conveyed his condolences to the families of the victims and to the government and people of Egypt. He stressed that no cause can justify such acts of terrorism and he calls on the perpetrators to be brought to justice.

"The United Nations remains fully engaged in supporting Egypt, an important member of this organization," the statement said. "The secretary-general is fully committed to supporting the Egyptian people's goal of a stable, democratic, prosperous Egypt."
