(CNN) -- Sunday was marked by a slew of anti-regime protests and yet more violence targeting dissenters in Syria, while outside the embattled country the leaders of the United States and Turkey discussed ways to aid the opposition. The bloodshed includes what the Local Coordination Committee of Syria, a network of opposition groups, is calling the "Morek Massacre." The group claimed that 11 civilians calling for the regime's ouster were murdered, among them five "executed by firing squad." In total, the LCC reported that at least 70 died across the Middle Eastern nation Sunday, including 17 in the province of Homs, 17 in Hama (where the town of Morek is located), 11 in Idlib, 10 in the suburbs of Damascus, nine in Daraa, five in Aleppo and one in Hasakeh.NEW: At least 70 people are killed around Syria on Sunday, an opposition group claims11 civilians die in the "Morek Massacre," 5 by firing squad, according to the same groupObama and Erdogan talk about providing medical supplies to the Syrian oppositionSyria state news says Russian foreign minister opposes interfering in internal affairs
