Nations mull tougher sanctions on Syria NEW: Russian food aid arrives in Syria At least 50 people have been killed Thursday in fighting, the opposition says Syrian religious endowments director has been kidnapped, state TV reports (CNN) -- World powers intent on regime change in Syria met to discuss sanctions on Bashar al-Assad's government Thursday. The meeting comes amid daily violence, including the kidnapping of a religious endowments director in the flashpoint Syrian province of Daraa, the birthplace of the uprising. Meeting at The Hague focuses on toughening sanctions The Friends of the Syrian People, a group of more than 60 countries working for regime change in Syria, considered tightening economic sanctions against the country's government Thursday. Participants include all the European Union countries, the United States, Canada, Australia, all the gulf states, Jordan, Turkey, the Arab League and other nations. They met at The Hague in the Netherlands. By imposing sanctions we are sending an important message and helping to further isolate the regime. But sanctions will only have an impact if they are carried out effectively. That is how we can make a difference," Dutch Foreign Minister Uri Rosenthal said. Rosenthal urged the countries to assess the sanctions they've imposed and determine whether stronger ones are needed. He noted many steps: strictures on the travel of top officials, freezing regime bank accounts and steps against the oil industry. He said the nations are trying to make sure arms aren't making their way into the country. The same applies to other products the regime can use to hurt its people -- everyday products for us, but for them, dual-use. Take the technology and equipment required to censor websites or track people online. To you and me, information and communication technology is an innocent tool we use every day. But we need to ensure it can't be used to commit violence or oppress the Syrian people," he said. Russian aid arrives A Russian aircraft carrying 38 tons of food supplies for beleaguered Syrians arrived in Damascus on Thursday, according to the state-run Syrian Arab News Agency, or SANA. Alexander Bogdanov, deputy director of the emergencies department at the Russian Ministry of Extraordinary Situations, said that the supplies included sugar, meat, milk and canned fish. "This aid is evidence of Russia's principled stances toward Syria and the strong and solid relations between the Syrian and Russian governments and peoples," said Hassan Hijazi, Syria's assistant minister of social affairs and labor. U.S. senator warns Iraq over airspace for Iran Sen. John Kerry, chairman of the U.S. Foreign Relations Committee, warned Iraq to avoid "fanning the flames of violence" by allowing Iran to use its airspace to transport weapons to Syria or face possible sanctions. Kerry's comments Wednesday follow reports that Iran has been sending weapons through Iraq to Syria, something Iraq has vehemently denied. Kerry raised the possibility of cutting off aid to Iraq if it didn't take steps to address the issue. Opposition reports burned bodies, dozens of deaths A reporter for the opposition's Shaam News Network was among four men who were killed and their bodies burned in Hama when regime forces set fire to a house, the news agency said late Wednesday. Adbelkareen Al'uqda, 26, used the monikers Abu Hassan and Karmo in reports, the network said. Deaths mounting At least 50 people were killed in fighting early Thursday, according to the Local Coordination Committees of Syria, an opposition group. Twenty-four of the casualties occurred in the city of Homs and 10 in Aleppo. State TV says regime forces killed Afghan "terrorists" Al-Assad's forces killed more than 100 foreign fighters, described as "Afghani terrorists," who were holed up at a school in Aleppo, SANA said. The news agency did not say when or how the fighters were killed, nor did it spell out details about how Syrian forces determined they were Afghan fighters. The operation took place in the Bustan al-Qasr neighborhood. Assassination, kidnapping, chopper crash A religious endowments director who oversees the provincial cities of Daraa and Sweida was kidnapped by an armed terrorist group, the label the al-Assad regime has given the opposition, SANA said. The report said terrorists in a car abducted Muammar al-Shahadat in Daraa. In Hasaka, "terrorists" shot and killed a government official, Marwan al-Husein, SANA said. He is head of the production department at the branch of the Military Housing Establishment in the city. State TV reported that a helicopter crashed southeast of the Damascus suburb of Douma, while the Syrian Observatory for Human Rights, an opposition group, said it was downed by rebels. In the interview, Larijani said that according to reports he received, there was contact with the Muslim Brotherhood of Syria "to bring about peace and to support necessary reforms." It was unclear when the discussions were held or whether they yielded any progress, though Larijani said they were held in Tehran. A Turkish military prosecutor says forensic evidence shows that the June downing of a Turkish jet by a surface-to-air missile fired by Syria occurred over international waters, the semiofficial Anadolu news agency reported. Syria shot down the F-4 Phantom jet on June 22, intensifying the animosity between the countries, whose once close relationship has eroded since al-Assad's forces began cracking down on the opposition last year. Syria said the plane violated its airspace, an allegation that Turkey vehemently disputed. CNN's Hamdi Alkhshali, Amir Ahmed and Joe Sterling contributed to this report.
