CAIRO, Jan. 27 (Xinhua) -- Egypt's President Mohamed Morsi imposed Sunday a curfew and a state of emergency in the turmoil- stricken Port Said governorate, as well as Suez and Ismailia, due to the ongoing bloody clashes there.

"I asserted earlier that if I had to, I would take any extraordinary measures to stop bloodshed, preserve security and protect the citizens," Morsi said in a televised speech Sunday evening, adding that the curfew in the three governorates would last 30 days, starting from 9:00 p.m. to 6:00 a.m. of the following day.

Over the past few days, the three governorates witnessed bloody confrontations between protesters and security forces.

On Saturday, at least 31 were killed and over 300 injured in clashes between police and angry mob in Port Said, after a court ruled the execution of 21 convicts in a local soccer riot that killed 74 early last year.

Besides, seven have been killed and over 630 injured so far on Sunday, also in Port Said, during a mass funeral for the victims of Saturday's clashes.

Meanwhile, eight were killed in Suez and one in Ismailia Friday in the similar clashes between protesters and security forces.

The Egyptian president attributed the bloody clashes to "sinful hands" that deviated from peaceful protest and expression of opinions to armed aggression and vandalism.

"I invite leaders of political forces for a dialogue Monday afternoon," Morsi said, stressing there was no alternative to a dialogue among the Egyptian people to overcome the ongoing crisis.

Egypt's main opposition bloc, the National Salvation Front (NSF) , demanded Morsi Saturday to amend the controversial recently- drafted constitution, form "a qualified national salvation government," sack the current Prosecutor-General Talaat Abdullah and subject the Muslim Brotherhood (MB) to the law, threatening to urge massive protests next Friday and to boycott the upcoming parliamentary elections.

The presidency issued a statement after Morsi's speech stating that the president invites 11 parties for Monday's dialogue, including al-Dostour Party headed by NSF leader Mohamed Elbaradei, the MB's Freedom and Justice Party, al-Wafd Party, Strong Egypt Party and others.

The invitation was also extended to leading opposition figures like former Arab League chief Amr Moussa, leftist ex-presidential candidate Hamdeen Sabahy, leader of Ghad al-Thawra Party Ayman Nour, etc.

埃及总统宣布塞得港等地进入紧急状态

新华网开罗１月２７日电（记者田栋栋　徐晓蕾）埃及总统穆尔西２７日晚发表全国电视讲话，宣布发生严重冲突的塞得港、苏伊士以及伊斯梅利亚省进入紧急状态并实施宵禁。

穆尔西在讲话中谴责针对所有公共和私人设施的破坏行为，称前一天有关塞得港球迷骚乱案件的判决是公正的，并不针对任何一方，呼吁所有埃及民众尊重司法机关权威。

穆尔西宣布，塞得港等地将从当地时间２７日午夜起进入紧急状态，将持续３０天，期间的宵禁将从每天晚上９点持续至第二天早上６点。

穆尔西同时邀请国内各个派别２８日在开罗举行对话，就当前的形势展开讨论。他还警告说，将采取一切必要措施维护国家安全与稳定。

连日来，埃及伊斯梅利亚、苏伊士、开罗等地爆发大规模民众示威抗议，一些示威者与安全部队士兵和警察发生激烈冲突，造成数百人受伤。２６日，塞得港刑事法庭在开罗警察学院宣判２１名去年塞得港球迷骚乱中的被告死刑，引发被告家属和支持者的愤怒，塞得港随后陷入混乱，激烈的冲突目前已致３８人死亡。

塞得港体育场去年２月１日晚举行开罗阿赫利队与塞得港埃及人队的一场足球赛，结果埃及人队以３：１获胜。赛后，两队球迷持棍棒等器械在体育场内外混战，造成至少７４人死亡、数百人受伤，震惊世界。埃及足协主席查希尔在骚乱发生后带领其领导的执行理事会成员于去年２月４日宣布集体辞职。
