Jailed Bahraini activist Abdulhadi al-Khawaja has been on hunger strike for a week seeking release, his lawyer said on Sunday, adding that authorities have arrested his daughter at the airport. "Abdulhadi is continuing with the hunger strike he began on August 25" in Jaw prison near Manama, said lawyer Mohammed al-Jishi. Jailed for life for plotting to overthrow the monarchy, 54-year-old Khawaja staged a 110-day hunger strike in 2012 over his imprisonment. Bahraini authorities said they will continue to monitor Khawaja's health.
