More than 300 people were detained in the Belarusian capital Minsk on Sunday, where crowds of people took to the streets for the 18th consecutive weekend, demanding the ouster of the country’s leader who won a sixth term in office in an election widely seen as rigged, AP reported.

Thousands of people Sunday took part in dozens of small rallies scattered all over Minsk—a new tactic the opposition employed instead of one large gathering to make it harder for the security forces to target the protesters.

Police in Minsk said they detained more than 300 people. The Viasna human rights group released the names of 215 people detained in Minsk and other cities, where rallies also took place.

Mass protests have rocked Belarus, a former Soviet republic in eastern Europe, since official results from the Aug. 9 presidential election gave Lukashenko a landslide victory over his widely popular opponent, Sviatlana Tsikhanouskaya. She and her supporters refused to recognize the result, saying the vote was riddled with fraud.

On Sunday, water cannons, armored vehicles, and military trucks were seen in the center of Minsk. Several subway stations were closed and internet access was restricted.

Protesters in the meantime say they aren’t discouraged by the crackdown.
