Berlin - German Chancellor Angela Merkel condemned on the Sunday the "brutal, inhumane" bombing that killed at least 53 people the day before in Islamabad.

"The fight against transnational terrorism remains a top priority for affected countries like Pakistan and the international community," she said in a Berlin statement.

"Germany will be continuing to support its partner Pakistan in efforts for stability and prosperity."

Germany's Foreign Minister Frank-Walter Steinmeier said in a condolence message to the Pakistan Foreign Ministry that everything must be done to "discourage support for the terrorists."

German diplomats said earlier that seven German nationals were among the injured in the blast. (dpa)
