Armenian police have arrested more than 30 people, including members of parliament, in the wake of post-election clashes between police and protesters on March 1 that left as many as eight people dead. More arrests may follow.

“The people who were arrested played a very negative role in last week’s violence, and they will be punished,” a spokesman for President Robert Kocharyan, Victor Soghomonian, said yesterday by telephone from the capital, Yerevan. “More arrests are expected.” The deadly clashes came after opposition parties had held 11 days of rallies since the presidential election, in which Prime Minister Serzh Sargsyan defeated Levon Ter-Petrosyan, a former president. Mr. Kocharyan responded by imposing a state of emergency. The opposition says the February 19 election was rigged.

Armenia’s parliament voted yesterday to strip four lawmakers of their immunity from prosecution. Two have been arrested and two are wanted by prosecutors, Foreign Ministry spokesman Tigran Balayan said in an emailed statement. All four are supporters of Ter-Petrosyan, Arman Musinyan, a spokesman for the former president, said by telephone.

The Constitutional Court began hearing a complaint filed by opposition politicians about falsification of election results. Mr. Soghomonian said the court will rule by Saturday.
