DAMASCUS - President Bashar al-Assad has insisted he will not step down and blasted Britain’s support for his foes, as opposition chief Ahmed Moaz al-Khatib visited north Syria Sunday and hundreds were reported killed in a battle.

“We are ready to negotiate with anyone, including militants who surrender their arms,” Assad told Britain’s Sunday Times newspaper in a rare interview conducted last week in Damascus. “We can engage in dialogue with the opposition, but we cannot engage in dialogue with terrorists,” he said in the videotaped interview. His offer of talks was aired as UN chief Ban Ki-moon and his Syria envoy Lakhdar Brahimi said they were prepared to broker peace negotiations between Assad’s regime and the opposition, after the two sides had proposed a dialogue.

Iranian Foreign Minister Ali Akbar Salehi said on Saturday that Assad, a close ally of Tehran, would contest a presidential election next year and it was up to the Syrian people to choose their own leader.

Syria is locked in a nearly two-year-old conflict in which the United Nations estimates that more than 70,000 people have been killed. But Assad rejected the idea of standing down to end the bloodshed.

“If this argument is correct, then my departure will stop the fighting,” he told The Sunday Times. “Clearly this is absurd, and other recent precedents in Libya, Yemen and Egypt bear witness to this.”

Assad accusing London of seeking to arm the rebels and ruled out any mediation role for Britain, saying: “We don’t expect an arsonist to be a firefighter.” British Foreign Secretary William Hague reacted to the interview by calling the Syrian leader “delusional” for failing to see that he was to blame for the carnage. Hague also said that he would this week announce more assistance to the Syrian opposition in the form of non-lethal equipment, and refused to rule out the possibility of arming them in the future.

“This is a man presiding over this slaughter,” he told BBC television. “We are the people sending medical supplies to try to look after people injured and abused by the soldiers working for this man.”

Asked about a reported Israeli air strike near Damascus in January, Assad said his country would retaliate. “Retaliation does not mean missile for missile or bullet for bullet. Our own way does not have to be announced,” he said.

On the ground in the mainly opposition-held north, opposition chief Khatib visited the towns of Menbej and Jarablos in Aleppo province, an opposition official told AFP. “Khatib entered the country for a few hours on Sunday morning for the first time” since becoming Syrian National Coalition chief in November, the source said on condition of anonymity. “He visited Menbej and Jarablos to view the situation of residents there and to discuss their living conditions,” said the official. “Khatib also held meetings with local officials in the two towns to discuss the (Aleppo) provincial election that is being held today (Sunday)” in the Turkish town of Gaziantep, the official said. The opposition-organised election for a council for Aleppo province is being held in Gaziantep for security reasons.

Meanwhile, the Syrian Observatory for Human Rights reported some 200 troops and rebels killed in eight days of fighting over a police academy in Khan al-Assal in Aleppo province, with insurgents seizing control of most of the complex.

The Britain-based group said at least 120 government troops were among those killed in the battle for one of the regime’s last remaining bastions in the west of the province. A police source in Aleppo confirmed that much of the academy had fallen into rebel hands.

Elsewhere, two mortar rounds hit an area near Umayyad square in the heart of Damascus, state media said, reporting only material damage. The area houses the state television complex, the Assad Library and the army general command.

Also on Sunday, rebels in the southern province of Daraa seized an artillery unit in Jamla village near the armistice line with Israel, the Observatory said.

At least 108 people were killed in violence across the country on Sunday, according to a preliminary toll from the Britain-based watchdog.

The six Gulf monarchies on Sunday criticised world inaction on Syria and Iranian “interference” in their internal affairs ahead of a visit to the Saudi capital by US Secretary of State John Kerry.

“The Syrian crisis has become more of a quasi-catastrophe through the unjustified killing of the Syrian people,” Bahraini Foreign Minister Sheikh Khaled al-Khalifa said at the opening session of a Gulf Cooperation Council (GCC) meeting.

Sheikh Khaled criticised “the international community’s lack of serious and rapid action” towards resolving the two-year conflict which the United Nations estimates has has cost more than 70,000 lives.

GCC members Saudi Arabia and Qatar have openly taken up the cause of the Syrian revolt and called for rebel forces to be armed in their battle against President Bashar al-Assad’s regime. The GCC nations also slammed what they charged was Iranian interference in their internal affairs.

Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Kuwait, and Oman “look forward towards better relations with Iran, but unfortunately the latter continues to interfere in their internal affairs,” Sheikh Khaled said. “It is important for our countries to stand united against such interference” from the Shia Islamic republic across the Gulf, he said.
