Turkish Prime Minister Recep Tayyip Erdogan on Tuesday said the Israeli air raids on Syria were "unacceptable."
"No excuse can justify this operation," Erdogan told ruling party lawmakers in parliament after Israel's weekend strikes on the war-torn country sent regional tensions soaring.
Israeli air raids killed at least 42 soldiers, according to monitoring groups, fuelling international concern over a spillover of the conflict, as Damascus warned it would strike back.
