AMMAN - Syrian tanks shelled residential areas in two towns and at least 19 people were killed across the country, rights campaigners said, as President Bashar al-Assad's forces fought to crush a seven-week uprising. Assad, fighting the most serious challenge to his 11-year rule, has sent troops and tanks into several cities in the last two weeks to try and end protests inspired by Arab revolts which toppled leaders in Egypt and Tunisia. Wednesday was one of the bloodiest days apart from the main Friday protest days, when thousands use the platform of weekly Muslim prayers to demonstrate. Most of the violence occurred in the southern Deraa province, where unrest erupted on March 18. Protesters, who first called for reforms and greater freedoms, have hardened their demands with many chanting for the overthrow of the president who inherited the authoritarian powers of his father Hafez al-Assad, who died in 2000. Ammar Qurabi, head of the National Organisation for Human Rights in Syria, said 13 people were killed in the town of Harra, about 60 km (40 miles) northwest of Deraa city. Most were killed when tanks shelled four houses. Two people – a child and a nurse – died in gunfire, he said. Tanks also shelled a residential district in Syria's third largest city Homs and at least five people were killed, a rights campaigner in the city said. A sixth person was killed by a sniper shot to the head as he stood in front of his house. "The security forces are terrorising urban centres," said Najati Tayara, the activist in Homs. There was no immediate comment from Syrian authorities, who have banned most international media from Syria, making it difficult to verify accounts of events. In Syria's second city Aleppo near the border with Turkey, security forces used batons to disperse a pro-democracy demonstration by 2,000 students on Wednesday at a university campus, a witness said. Another resident of Aleppo said secret police had closed the main road leading from the centre of the city to the campus in the western Furqan district. The violence has been denounced in the West, where countries have imposed limited sanctions on Syrian leaders but stopped short of calling for Assad to step down, as they have in the case of Libya's Muammar Gaddafi.
