Why PM's sympathy only for Khaleda Zia?

Arafat Rahman Koko died of cardiac arrest. After that, we saw the PM go to BNP's Gulshan office to offer her condolences to Khaleda Zia (though she was not allowed to enter the BNP office). My question is why offering condolence to Khaleda Zia only? Why not all the mothers of the victims who died due to arson attacks perpetrated by BNP-Jamaat? Because their mothers are not the ex-PMs and ex-opposition leaders?

The mothers of the victims who died in the recent violence deserve the PM's condolences too.
