UN sounds alarm over arrests of Afghan activists speaking up for women, girls.

The Taliban authorities in Afghanistan must immediately release activists detained for advocating for girls' and women's rights, the UN human rights office, OHCHR, said Wednesday, expressing alarm over the ongoing arrests.

Since the beginning of the year, several civil society activists and journalists have been detained for speaking out against Taliban policies that restrict women and girls' access to education, work, and most other areas of public life.

'No one should be detained for speaking out in defence of their fundamental rights and the rights of others,' OHCHR Spokesperson Jeremy Laurence said in a statement issued in Geneva.

'Arrest or detention as punishment for the legitimate exercise of fundamental rights, such as the rights to freedom of opinion and expression, is arbitrary under international human rights law,' he added.

The statement comes in the wake of the latest arrest, which occurred on Monday, according to OHCHR.

Matiullah Wesa, head of PenPath, a civil society organization campaigning for the reopening of girls' schools, was detained by unidentified individuals who were travelling in an unmarked vehicle. His whereabouts are unknown.

The same persons also entered Wesa's home the following day and seized two of his brothers, who were released several hours later.

The OHCHR said other activists and journalists had also been detained with no clear information as to their whereabouts, well-being or any charges against them.
