Cairo - Egypt's embattled president on Friday dismissed calls for early presidential elections as clashes erupted in a northern Egyptian city and unidentified assailants torched a Cairo campaign headquarters of a youth group petitioning for Mohammed Morsi's removal from office.
The developments come as tensions rise ahead of 30 June, when Morsi marks one year in power as Egypt's first freely elected president following the 2011 uprising that toppled autocrat Hosni Mubarak.
In a four-page interview with the state-run Al-Ahram daily ahead of the anniversary, Morsi said demands for an early presidential vote are both "absurd and illegal." He also warned against violence during upcoming demonstrations, which the opposition plans for the anniversary to demand his ouster.
"Violating the law, the use of violence or inciting for it are unacceptable and will not be permitted," Morsi told the paper on Friday. "We are in a country with a constitution and law. We had free and fair elections and the talk about early presidential elections is absurd and illegal."
The lengthy interview was a throwback to Mubarak's era when the paper served as a government mouthpiece, glorifying the regime's perceived successes and never challenging authorities.
Before dawn on Friday, attackers stormed and partially torched the down town Cairo headquarters of a volunteer youth group running a petition calling for Morsi's removal from power.
The drive, known as "Tamarod" or "Rebel" in Arabic, is helping galvanize an opposition that has long been in disarray and demoralised. So far, the volunteers say they have collected about 7 million signatures.
They hope to collect 15 million signatures and believe that such a large number would force Morsi out of office by 30 June. The figure would be 2 million more than the number of votes Morsi garnered in last year's presidential election, which he won with 52% of the votes. Egypt's population is around 90 million.
The volunteer group said it had received threats prior to the 03:30 attack, alerting some activists to stay overnight at the office.
"We were awakened by someone trying to break the door and the glass and then we saw fire under the door, coming at us," said Hassan Shahine, one of the campaign founders.
Shahine, who suffered light burns trying to extinguish the fire, blamed Morsi's Muslim Brotherhood for the attack, saying the president's party is "the only one who would think of doing this." The volunteers filed a police complaint against Brotherhood leaders after the attack, he added.
A Brotherhood spokesperson, Mourad Aly, dismissed the accusations, saying the group has no reason to "burn the office of a group [of activists] as weak as this."
In a separate incident, women activists accused the Brotherhood of attacking them while attending a conference organised by the group in the Nile Delta city of Damanhur, 136km north of Cairo on Thursday night.
Video clips circulating on social networking sites showed bearded men wearing helmets at the site shouting "Allah Akbar," or God is Great, while carrying sticks and hurling rocks. The identity of the men is not clear. The website of the Brotherhood's political party said anti-Morsi activists were the ones who assaulted conference attendees.
Activist Hadir el-Sharkawi said Brotherhood members "beat us up and sexually harassed women including one who was stripped of her trousers." She said security personal were present but did not intervene.
The Brotherhood's Aly denied the allegations, saying "we are not going to delve into every single accusation".
During Morsi's tumultuous year in power, Egypt has witnessed deadly bouts of violence and mass street protests while the country's economy plummets and security woes worsen.
Egypt's liberal and secular-minded opposition accuses Morsi and the Brotherhood of causing deep polarisation among Egyptians. It says the president has not fulfilled his promises of creating an inclusive political process and instead has been enabling his Brotherhood to monopolise power.
For their part, Morsi and the Brotherhood say the opposition has no grass-roots support and seeks to unseat the president through street protests and violence after failing at the ballot box.
The opposition recently accused the Brotherhood of trying to divide it after a prominent member, Khairat el-Shater, met with Amr Moussa, a leading member of the opposition National Salvation Front - in a rare meeting of high-ranking rivals.
In a statement afterward, Moussa said he went to tell el-Shater that upcoming protests will be peaceful and that demands for early presidential elections are "legitimate." The Brotherhood said the meeting was designed to "break the ice" between the two sides.
Over the past months, thousands of volunteers have hit the streets across Egypt to win signatures for the anti-Morsi petition, being attacked on several occasions allegedly by the president's supporters.
The campaign has also provoked a counter-drive, called "Tajarod" or "Impartiality," which has gathered millions of signatures in Morsi's support. The group was quoted by daily al-Masry al-Youm on Thursday as saying it will hold a sit-in in front of the presidential palace starting 28 June to protect the building from rival groups.
A meeting of the two sides at the palace could end up in violence such as that which left ten dead in December, when clashes broke out at the site between supporters and critics of the Brotherhood.
At the Cairo offices of the anti-Morsi petition on Friday, the front door and ceiling were blackened from fire and ashes covered the floor. The group pledged to press on with its campaign, planning to bring the petition to the Supreme Constitutional court to lobby for new elections once it gathers 15 million signatures.
There would be no legal basis for such new elections however the opposition hopes a large turnout of protesters will help press the campaign's demands. Morsi's term lasts another three years.
