BEIRUT — Activists say Syrian troops are storming a central town and a northwestern region in search of opponents of the government.

The attacks on the town of Shezar and the Jabal al-Zawiya region near the Turkish border come a day after Syria agreed in principle to allow Arab observers into the country to oversee a peace plan proposed by the 22-member Arab League.

The British-based Syrian Observatory for Human Rights and the Local Coordination Committees said the latest attacks occurred early Saturday.

Syria's acceptance came on Friday after surprisingly heavy pressure from the Arab League, which brokered the plan and this week suspended Syria from the 22-member organization for failing to abide by it.
