My friend KHAN M ANJUM had just returned (2 days before the earthquake) to Pakistan from Malaysia. I have been trying to contact him via email since the day it happened but to no avail. I just want to know if he is ok. Thank you.
We are worried about our friend Enrique Lafargue, who was living at Margala Towers. Please contact us about any comments. Thank you.
I am worried about my in-laws, and praying for them. My father-in-law's name is Manzoor Qureshi, my mother-in-law's is Mubarak, and their family are Ijaz Mansoor, Shahid Masood, Bilal Maqsood, Ayaz Mahmood, Rabia, Safia, Zakia, Atia, and assorted spouses (Atia is a widow) and children, some of whose names I do not know because we have lost touch since I and my husband separated. I have no grudge or feeling of resentment against any of my in-laws, and long to know that they are all right. They used to live in Rawalpindi (next to Islamabad) and probably still did/do.
