Three villages fall in morning hours and town of Khan Sheikhoun is being shelled relentlessly BEIRUT: Syrian forces gained more ground from insurgents in the country’s northwest on Thursday, edging closer to a major opposition-held town a day after militants shot down a regime warplane in the area. The regime offensive, which intensified last week, has displaced nearly 100,000 people over the past four days, according to the Syrian Response Coordination Group, a relief group active in northwestern Syria. Syrian troops have been on the offensive in Idlib and its surroundings, the last major opposition stronghold in Syria, since April 30. The region is home to some 3 million people, many of them displaced in other battles around the war-torn country. The fighting over the past days has been concentrated on two fronts as regime forces march toward the town of Khan Sheikhoun from the east and west. The latest offensive also aims to besiege opposition-held towns and villages in northern parts of Hama province, according to opposition activists.The town of Khan Sheikhoun is a stronghold of Hayat Tahrir Al-Sham, the most powerful group in the opposition-held areas. The town was the scene of a chemical attack on April 4, 2017 that killed 89 people. At the time, the US, Britain and France pointed a finger at the Syrian regime, saying their experts had found that nerve agents were used in the attack. Days later, the US fired 59 US Tomahawk missiles at the Shayrat Air Base in central Syria, saying the attack on Khan Sheikhoun was launched from the base. The Syrian regime and its Russian allies denied there was a chemical attack. The regime-controlled Syrian Central Military Media said on Thursday pro-regime forces captured three small villages, just west of Khan Sheikhoun. The Britain-based Syrian Observatory for Human Rights, a war monitoring group, said the villages fell in the morning hours and that the town of Khan Sheikhoun is being bombarded relentlessly. Syrian state media confirmed that opposition fighters had downed the regime plane on Wednesday. An Al-Qaeda-linked group has released a video of the pilot in which the handcuffed man identified himself as a lieutenant colonel in the Syrian air force. In the video, the pilot says his fighter jet was shot down when he was carrying out a mission near Khan Sheikhoun.
