The people of war-torn Sudan learned long ago to take cover when planes roared overhead, but the latest tactic being used on them — parachute bombs — is raining silent death down on innocent villagers, say alarmed activists.

The country’s extremist Islamic regime in Khartoum has stepped up the practice in the Nuba Mountains, dropping deadly bombs by parachute from high altitudes as president and accused international war criminal Omar al-Bashir seeks to rout rebel forces opposed to his brand of radical Islam.

In recent years, the Nuba Mountains, where Christians and Muslims live side by side, have become a battleground for the forces of al-Bashir’s forces and the Sudanese People Liberation Army.
