Republican and Democratic U.S. lawmakers said on Thursday they would keep up their push for tougher sanctions on Turkey over its offensive in Syria despite the announcement of a five-day cease-fire.

Republican Sen. Lindsey Graham and Democratic Sen. Chris Van Hollen announced legislation that would impose ¡°crippling¡± sanctions on the government in Ankara shortly before U.S. Vice President Mike Pence and Turkish President Recep Tayyip Erdogan said Turkey had agreed to a pause to let Kurdish forces withdraw from a ¡°safe zone.¡±

The bill would target Turkish officials, end U.S. military cooperation with the NATO ally and mandate sanctions over Turkey¡¯s purchase of a Russian S-400 missile defense system.
