Pro-Kurdish demonstrators rally in London on Tuesday, May 15, against Turkish President Recep Tayyip Erdogan and Ankara's military engagement in the Syrian crisis. The protest has been countered by a rally in support of the Turkish president, with clashes being reported.
Turkish troops, in cooperation with opposition groups loyal to Ankara, have participated in a number of military operations in Syria, mostly against Kurdish militants, such as the Olive Branch operation in Afrin and the Euphrates Shield held from August 2016 to March 2017. Damascus has condemned the Turkish military operations, saying they violate Syrian sovereignty.
