The motives behind Turkey's worst wave of violence in decades are varied. On Saturday, a bus carrying soldiers was blown up. On Monday, Russia's ambassador was shot dead near the parliament building. The building itself had been bombed by warplanes during July's botched coup.
Yet the response of those close to Recep Tayyip Erdogan after each attack is the same. They say the president must be granted executive powers that currently reside with parliament to help restore order.
Though Erdogan is already powerful, it might be working. Fears of deepening chaos have helped secure the backing of a conservative nationalist party, and public support for a presidential system has risen to 52 percent from 37 percent in June, according to Adil Gur, head of the A&G polling company.
