The document summarizes recent political developments in Yemen, Iran, Somalia, and Pakistan. In Yemen, the death of former president Ali Abdullah Saleh led to splintering within the General People's Congress party. In Iran, recent anti-government protests have lost momentum due to crackdowns by security forces and lack of centralized leadership among protesters. In Somalia, escalating tensions between the federal government and the powerful Habar Gedir clan are destabilizing the central government. In Pakistan, Islamist political parties are leveraging tensions between the US and Pakistan to gain popularity ahead of 2018 elections.
