At least 35 people were killed in Syria on Monday when a series of explosions took place in government-controlled areas and a city held by Kurdish militants, Reuters reported quoting state news agency SANA. The terror attacks have not been claimed by any group yet.

Earlier in the day, at least 11 people died in a string of blasts in Tartous and Homs. More than 45 people were injured in two explosions carried out near the Arzouna bridge in Tartous. The Syrian Observatory for Human Rights confirmed the attacks that included a car bomb explosion and a suicide bomb explosion.

Reuters reported that the Tartous Summer Festival was underway and that the the coastal town was recently promoted in a government campaign on social media, which invited people to visit the beaches in the region.

For more five years now, a civil war has divided Syria into several territories held by the government and a number of armed groups, including the so-called Islamic State. According to the news agency report, state television quoted a police commander, who said one person died and three were injured in an explosion that took place near al Saboura town, along a road that leads to the Beirut-Damascus highway.

The observatory reported an explosion, involving a motorbike in the Kurdish YPG militia-controlled city of Hasaka, where three members of the group's security force were killed and several others injured. The militia group, a vital component of a US-supported campaign against the Islamic State, took over Hasaka in August. The YPG also dominates a large part of northern Syria.

Bilateral negotiations between US and Russia, held on the sidelines of the G20 Summit in China, have come to naught on the issue of a temporary ceasefire in the war-torn country, BBC quoted US officials. AP, however, reported that a senior US official said Russian President Vladimir Putin and US President Barack Obama would keep working on reaching an agreement.
