The Latest developments on the war in Syria and the tens of thousands of Syrians fleeing violence (all times local):

Turkey's prime minister is calling on the international community to speak out against Russia for "mercilessly bombing civilian targets" in Syria.

Prime Minister Ahmet Davutoglu also says Tuesday that Russia will eventually retreat from Syria in "embarrassment" — in a similar manner to the Soviet forces who once left Afghanistan.

Davutoglu was speaking to legislators of his ruling party as tens of thousands of Syrians who fled a Russian-backed Syrian onslaught around the city of Aleppo massed at the border with Turkey.

Turkey is already home to 2.5 million Syrian refugees. Davutoglu insisted that Turkey has not shut its borders to refugees even though it has not let in the new wave of arrivals. A senior government official said Turkey would care for the Syrians within their borders "as much as possible."

Syrian state media says a car bomb has exploded near a police officers' club in the Syrian capital of Damascus, wounding at least eight people.

The SANA news agency says the blast went off near a vegetable market in the northern neighborhood of Masaken Barzeh. State TV said the blast occurred near a police officers' club, inflicting casualties.

The opposition Britain-based Syrian Observatory for Human Rights, meanwhile, said the blast killed eight policemen and wounded 20 after it was detonated in the parking lot of the officers' club.

Such attacks are not uncommon in the Syrian capital, the seat of power of President Bashar Assad.

The blast came a day after an international rights group said Syrian government forces and the Russian military have been carrying out daily cluster bomb attacks over the past two weeks in Syria, killing 37 people. The Human Rights Watch report said that cluster munitions, which are widely banned, have been used in at least 14 attacks across five provinces since Jan. 26.
