KABUL, Ramadan 5m 1436 AH, June 22, 2015, SPA -- A Taliban suicide bomber and several gunmen attacked the Afghan parliament on Monday, shattering windows and forcing lawmakers to flee, as a second district in two days fell to A group in the north, Reuters reported. Violence has spiralled in Afghanistan since the departure of most foreign forces at the end of last year and the fall of the second district raises questions about the NATO-trained Afghan security forces' ability to fight the Taliban. Insurgents are pushing to take territory more than 13 years after the U.S.-led military intervention that toppled the Taliban from power. "A suicide bomber blew himself up just outside the parliament building and several fighters took positions in a building close to parliament," said Ebadullah Karimi, spokesman for Kabul police. Afghan security officials said all lawmakers were safe. Taliban spokesman Zabihullah Mujahid claimed responsibility. -- SPA 11:12 LOCAL TIME 08:12 GMT www.spa.gov.sa/w
