At least 74 people were killed when supporters of two local Egyptian teams clashed on Wednesday, Reuters reported.

The incident is considered to be the deadliest since the fall of ousted president Hosni Mubarak.

Nearly 1,000 more people were wounded when football fans stormed the pitch when al-Masry beat Al Ahli 3-1.

Politicians blame security forces for failing to prevent the incident and killing of dozens of people.

"The military council wants to prove that the country is heading towards chaos and destruction," A 30-year-old laboratory technician and member of the Coalition of Revolutionary Youth said. "They are all Mubarak's men."

Meanwhile head of the Egypt's military council Hussain Tantawi regretted the incident and declared three days of national mourning.

"I deeply regret what happened at the football match in Port Said. I offer my condolences to the victims' familes." Mr Tantawi said.

Meanwhile, Egyptian Interior Minister Mohammad Ibrahim said that at least 47 people were arrested in connection with organising the incident.

Egypt is in the process of transition from a dictatorship to a democratic state after months of protests against Hosni Mubarak's regime.

At least ten security forces and forty militants were killed during clashes in the Kurrum agency of Pakistan on Tuesday, Pakistani media reported.

Thirty two other security forces were also injured during the clashes, officials said.

Officials said that the helicopter gunships were mobilised when the fighting broke out in the Jogi area and six soldiers were killed on January 25 in the district of Kurram, part of Pakistan's lawless tribal belt along the Afghan border.

Security forces claimed to have taken control of Jogi, which is strategically located near Orakzai district.

Pakistani officials added that more than 300 insurgents attacked the checkpoint at midnight in central Kurram.
