On 4 December, a bomb squad in Madrid destroyed a grenade which had been thrown over the wall of a migrant centre for children. Police said it was a training grenade containing a small amount of explosives, and no injuries were reported. The centre houses dozens of unaccompanied minors, many of them immigrants. The attack has been widely condemned by Spanish politicians and human rights campaigners, with many linking it to anti-immigrant rhetoric. During a televised election debate in November, the leader of the far-right Vox party, Santiago Abascal, accused youths at the centre of causing a spike in crime in the surrounding neighbourhood, where he lives. In the election, Vox more than doubled its seats to become the country's third most-powerful party.
