The death toll has risen to 92 people after a mosque suicide bombing which targeted policemen in the city of Peshawar in Pakistan.

In December the Pakistani Taliban targeted a police station - like Peshawar, in the north-west, bordering Afghanistan- which officials said had led to the deaths of 33 militants.

An entire wall of the building collapsed, and the mosque was covered in bricks and debris as people clambered over the rubble to escape.

On Monday, the president of the United Arab Emirates, Mohamed bin Zayed Al Nahyan, was due to visit Islamabad - although the trip was cancelled at the last minute because of bad weather.

On Tuesday, an International Monetary Fund delegation is meant to visit Pakistan as part of the process to unlock a bailout loan to prevent the country from defaulting.

In the capital Islamabad, police issued a high alert and said security at all entry and exit points to the city had been increased.
