RIYADH: Saudi Arabia said it was deep saddened over the collision of two passenger trains in the southern Pakistani province of Sindh, which killed and injured several people. An express train barreled into another that had derailed in Pakistan before dawn Monday, killing at least 51 people and setting off a desperate effort to search the crumpled cars for survivors and the dead, authorities said. More than 100 other people were wounded. The Ministry of Foreign Affairs “expressed its sincere condolences and sympathy to the families of the dead, and to Pakistan, the leadership, government and people,” wishing the injured a speedy recovery.
