The manner in which the government has handled the detention of Dr Akmal Waheed and Dr Arshad Waheed is questionable beyond doubt. Their appearance before an anti-terrorism court on Saturday came more than two weeks after they had disappeared.
The complete silence of the authorities until Friday, when a senior Karachi police official finally confirmed that the two were in their custody, is inexplicable.
While the need to detain and interrogate people suspected of having links with terrorist organizations may be there, the manner in which those detained are held incommunicado by security agencies cannot be condoned. One can imagine the trauma that families go through in such cases, waiting to hear about the whereabouts of their loved ones.
While the two doctors deny any wrongdoing, as a rule, medical practitioners who treat gun-shot wounds and similar injuries should notify the police. But failure to do so should not mean a licence for the authorities to pick them up and keep them in secret custody for long periods.
The doctors' family spoke of the cloak-and-dagger methods used by the security agencies - like trying to lure them to the US, and after their disappearance, making phone calls demanding ransom to make it look like a kidnapping case. These are reprehensible methods.
Since 2001, over 450 persons have been arrested in the country and handed over to the US authorities for further questioning. In most such cases, the next of kin were kept in the dark.
This gives ammunition to those who are opposed to the government's drive against Islamic militants. Take the case of the arrest of a Lahore-based surgeon, Dr Amer Aziz, in 2002, of scientist Aafiya Siddiqui, businessman Saifullah Paracha and journalist Khawar Mehdi in 2003.
While Dr Siddiqui remains untraced, the rest of them were kept in prolonged detention before their whereabouts were finally made known. This practice must stop. Instead, the due process of law needs to be observed under which those arrested are charged and brought before a magistrate or court within a reasonable period of time. This should be the rule not the exception.
Sri Lanka: peace in danger
The already fragile Sri Lankan truce hit yet another snag as the rebel Tamils informed Norwegian peace broker Erik Solheim that negotiations with the government could not progress so long as the latter continued to support a breakaway rebel faction.
The Tamil Tigers have accused the government of abetting Colonel Karuna, who earlier this year defected from the LTTE, the main rebel organization, and who had wanted to set up a separate regime in the east of the island.
This is seen as jeopardizing LTTE hopes of domination in the north and east. The Sri Lankan government has denied that it was harbouring the renegade leader, who has been accused of masterminding attacks on LTTE positions from army safe-houses, although it has admitted that some elements in the army might have been involved in the affair.
It is a pity that the peace process, delicately assembled by the Norwegians, the Tamils and the government, should once again be threatened by a possible renewal of violence.
Indeed, the fruits of cooperation, after two decades of bloody civil war that left at least 60,000 people dead and another million displaced, are there for all to see. The Tamils withdrew their demand for a separate state in return for regional autonomy, and the government, too, lifted a ban on the Tamil rebels.
A permanent ceasefire was signed in 2002, and a series of internationally hosted talks paved the way for crucial decisions on power-sharing and other issues. But last year, the Tamils suspended peace talks, and recent elections in Sri Lanka, which brought in a minority government - many elements of which are not in favour of concessions to the Tamils - have complicated matters and impaired trust between the two sides.
It remains to be seen whether the government and the Tamils, prodded by the Norwegians, can rise above their differences, and make compromises for peace. Or else, the island will find itself caught in a cycle of bloodshed once again.
