Top Iran official warns protests could destabilize countryDUBAI, United Arab Emirates (AP) — Iran’s parliamentary speaker warned Sunday that protests over the death of a young woman in police custody could destabilize the country and urged security forces to deal harshly with those he claimed endanger public order, as countrywide unrest entered its third week.Parliament Speaker Mohammad Bagher Qalibaf told lawmakers that unlike the current protests, which he said aim to topple the government, previous demonstrations by teachers and retirees over pay were aimed at reforms, according to the legislative body’s website.Qalibaf said he believes many of those taking part in recent protests had no intention of seeking to overthrow the government in the beginning and claimed foreign-based opposition groups were fomenting protests aimed at tearing down the system.Witnesses said security was tight in the areas nearby Tehran University and its neighborhoods downtown as hundreds of anti-riot police and plain clothes with their cars and motorbikes were stationed on junctions and squares.The protests have drawn supporters from various ethnic groups, including Kurdish opposition movements in the northwest of Iran that operate along the border with neighboring Iraq."
