Images posted on social media appear to show the destruction of
about a dozen places of worship across northern Iraq, in areas recently
taken over by extremist militants.
Some images showed the al-Qubba Husseiniya, a Shia shrine, being blown up in the city of Mosul.
Militants used a bulldozer to destroy a shrine known as the "Girl's Tomb" in Mosul.
They believe giving special veneration to graves and relics is against the teachings of Islam.
Militants also destroyed the Saad bin Aqeel Husseiniya shrine in Tal Afar, approximately 50 km (35 miles) west of Mosul.
The militants, believed to belong to Isis (Islamic State of
Iraq and the Levant), are also reported to have attacked churches in
Mosul.
More images showed the Ahmed al-Rifai shrine and tomb in the Mahlabiya district near Tal Afar being attacked with a bulldozer.
The militants have attacked Shia and Sunni shrines alike, and
have vowed to continue destroying places of worship which they do not
approve of.

The STM32 GPIO is blazingly fast and the built-in DMA controller looks powerful enough to handle high bandwidths. So having that in mind, we spent several months perfecting both software and firmware side and here is what we got in the end. Capturing the signals The main challenge when using a microcontroller like STM32 as a core of a logic analyzer is dealing with sampling irregularities. Unlike FPGA-based analyzers, the microcontroller has to share the same resources to load instructions from memory, read/write th...
